Red Spotted Severum Cichlid (Heros notatus) - UK

The Spotted Severum Cichlid, Heros notatus, is one of the most rewarding large South American cichlids you can keep if you want a fish with presence, intelligence, and a calmer nature than many aggressive cichlid species. For aquarists searching for tropical fish for sale UK, this distinctive severum stands out for its elegant spotted pattern, rounded body shape, and adaptable personality in a well-planned aquarium. Native to the Rio Negro and Essequibo systems, this South American cichlid UK choice reaches around 20 cm, can live up to 10 years, and thrives in soft, slightly acidic water. It is often recommended for keepers moving beyond small community tropical fish UK species and into the world of larger display fish.

If you want to buy fish online and are comparing options like a Red Spotted Severum, wild type severum for aquarium, or other rare tropical fish for sale UK listings, Heros notatus offers a more natural, understated beauty. It is not a coldwater species, so anyone browsing cold water fish for sale uk should look elsewhere. Instead, this is a true tropical cichlid for a mature heated aquarium. See our detailed photos showing body shape, spotting, and finnage in our product image gallery, including the featured image tropical-fish-for-sale-uk.webp. For aquarists who want a hardy, characterful freshwater tropical fish for sale uk specimen with graceful movement and manageable care, the Spotted Severum is an excellent centrepiece fish.

Where Do Spotted Severum Cichlids Come From? Natural Habitat Explained

The Wild Severum form of Heros notatus comes from northern South America, especially the Rio Negro basin and the Essequibo drainage. These waters are often tea-stained by tannins from leaf litter and wood, with soft mineral content and a naturally acidic profile. That origin explains why severum water conditions matter so much in captivity. Although severums are adaptable, this species does best when you respect its blackwater roots rather than keeping it in hard, alkaline water.

In the wild, this fish moves through slower margins, flooded forest areas, and root-filled channels where it can browse for plant matter, algae films, small invertebrates, insect larvae, and organic debris. This natural browsing behaviour shapes the ideal spotted severum diet in the aquarium too. They are not open-water speedsters; instead, they cruise the middle levels, investigate décor, and use structure for security. That is why a spotted severum for large aquarium setup with wood, shaded areas, and calm open swimming space works so well.

Many aquarists searching terms like buy Heros notatus UK, buy notatus severum UK, buy spotted severum UK, live notatus severum UK, or live spotted severum UK are specifically looking for this more natural severum type rather than heavily selected colour strains. It appeals to keepers who enjoy authentic fish behaviour and a biotope-inspired display. In the UK hobby, it is often seen as a rare cichlid UK option and even a rare severum variety UK because it is less commonly offered than gold or red morphs.

If you are comparing a red spotted severum for sale UK listing with a true notatus-type fish, the main difference is emphasis: the notatus fish is prized for pattern and natural elegance, while line-bred strains are chosen for stronger red or gold tones. Either way, this is a large cichlid UK fish that needs room, stable water, and thoughtful tank mates. It is not suitable for tiny starter tanks or novelty setups like home aquarium sharks uk searches often suggest.

How to Set Up the Perfect Tank for Spotted Severum Cichlids

Getting the setup right is the biggest factor in long-term success with this species. When aquarists ask about severum minimum tank size or severum tank size, the practical answer is 300 litres as a true minimum for one adult or a bonded pair in a carefully planned layout. For mixed cichlid communities or if you want the fish to reach full confidence and body depth, 450 litres or more is better. A common mistake is assuming a juvenile can stay in a small tank permanently. A young fish may arrive at only a few centimetres, but red spotted severum full grown size is substantial, and body depth matters as much as length.

Tank Size Requirements

The ideal red spotted severum tank size or notatus setup depends on stocking. A single specimen can work in 300 litres, but a pair or a mixed severum community tank should have more floor space and swimming room. Because these are deep-bodied fish with moderate bulk, they produce a noticeable bioload. If you are browsing large tropical fish tanks for sale uk or tropical fish tanks for sale uk, think long and wide rather than tall and narrow. A tank around 120 x 45 x 55 cm is a practical starting footprint, while larger is always safer for territory management.

Water Parameters

Stable water quality matters more than chasing extreme values, but the best severum water parameters for Heros notatus are closely aligned with its natural habitat. Aim for 24-28°C, with the spotted severum ideal temperature around 25-27°C for general care. If you are checking red spotted severum temperature or general severum temperature advice, those same values apply to most severum types. Keep pH between 5.5 and 7.0, with a preferred severum pH level of roughly 6.2-6.8. For hardness, severum water hardness should ideally stay between 2 and 12 dGH, with softer water often giving better condition and breeding response.

Filtration

Use oversized filtration with strong biological capacity rather than harsh torrent-like flow. External canister filters are ideal for severums because they handle waste well and keep the display uncluttered. A turnover of 4-6 times tank volume per hour is a good target. Add spray bars or directional outlets to diffuse current. This species comes from calmer waters, so the goal is clean water, not river-tank turbulence. Pair your setup with a reliable aquarium heater and thermometer for stable severum freshwater conditions.

Substrate

Fine sand or smooth rounded gravel works best. Severums may mouth substrate and move light décor, especially during pair formation or spawning. Darker substrate usually improves confidence and helps the pattern stand out. Avoid sharp gravels that can damage the mouth. If you are creating a natural South American display, driftwood and leaf-litter tones complement this fish beautifully.

Plants & Decor

Many keepers ask whether Heros notatus for planted tank setups can work. The answer is yes, but choose robust species and expect some nibbling. Tough plants attached to wood or rock are safer than delicate stems. If you are shopping for tropical fish tank plants for sale uk or tropical fish plants for sale uk, look for hardy options suited to cichlid tanks rather than fragile carpeting plants. Searches for tropco plants are common among aquarists building natural displays, but whatever source you use, focus on durable species and secure planting. Driftwood arches, root tangles, and broad leaves create sight breaks that reduce tension between severum tank mates.

If you enjoy comparing related cichlids while planning your display, take a look at the Red Head Severum Cichlid - Heros and Heros Sp. Rotkeil - Redneck Severum for alternative severum forms.

Lighting Requirements

Moderate lighting is ideal. Bright, exposed tanks can make severums skittish unless the layout includes shade from wood or floating cover. Run the lights for 7-9 hours daily. Warm-spectrum lighting often brings out the bronze, olive, and spotted patterning better than very cool white light.

What Do Spotted Severum Cichlids Eat? Complete Feeding Guide

Heros notatus is an omnivore with a strong appetite for both prepared foods and vegetable matter. In nature, it grazes on plant material, biofilm, small invertebrates, and organic matter. Good spotted severum feeding should reflect that variety. A quality cichlid pellet should form the staple diet, supported by spirulina-based foods, blanched vegetables, and occasional protein-rich treats. This balance helps maintain digestion, body shape, and colour without pushing the fish into fatty degeneration.

Staple Foods

Use a high-quality medium to large cichlid pellet as the base. Choose formulas with balanced protein and some plant content rather than very rich predator foods. Severums are often suggested for aquarists moving beyond small fish, but they are still among the better tropical fish for beginners in the large cichlid category because they usually accept prepared foods readily.

Supplemental Foods

Supplement the staple diet with blanched spinach, shelled peas, courgette, and spirulina flakes. Frozen foods such as bloodworm, mysis, krill, and brine shrimp can be offered a few times weekly. This is especially useful when conditioning a spotted severum breeding pair. If you regularly keep larger cichlids and are used to buying fish food alongside your livestock when you buy tropical fish UK, choose foods aimed at omnivorous cichlids rather than carnivore-only formulas.

Treats & Special Foods

Treats should be occasional. Too much fatty food can lead to bloating and poor water quality. Colour-enhancing foods can help bring out warm red and gold tones in line-bred forms such as red spotted gold severum, super red severum, or super red spotted severum, but natural pattern and health always depend more on stable water and a varied diet than on artificial colour boosting.

Feeding Frequency & Portion Control

Feed juveniles 2-3 small meals daily and adults 1-2 measured meals. Offer only what they can finish in around 30-60 seconds. This species is greedy and will quickly learn to beg, but that does not mean it needs more food. Good portion control is one reason severums often outlive more heavily overfed cichlids.

Time	Food	Amount
Morning	Cichlid pellets with spirulina content	Small portion, fully eaten within 1 minute
Evening	Vegetable mix or frozen food rotation	Small portion, no leftovers

People often compare this species with smaller fish sold in tetras for sale uk or tetra fish for sale uk searches, but feeding needs are very different. Severums need larger, more substantial foods and should not be treated like tiny community fish. They also are not suitable for a freshwater fish bundle or tropical fish bundles style impulse purchase unless the tank is already mature and appropriately sized. If you are deciding between this species and fish commonly listed under fish for sale pets at home, tropical fish pets at home, or all pond solutions tropical fish, remember that the severum is a long-term display fish, not a casual add-on.

What Does the Spotted Severum Look Like? Colors, Patterns & Varieties

The Spotted Severum Cichlid has the classic severum profile: a tall, laterally compressed body, rounded forehead, and elegant dorsal and anal fins that mirror the body curve. Adults typically reach around 20 cm, though body depth makes them appear larger than many fish of the same length. The base colour is usually olive, bronze, or greenish-brown with a pattern of darker spotting or broken lateral markings that gives the species its name.

Spotted severum behaviour also affects appearance. A relaxed fish shows clearer pattern, richer body tone, and smoother finnage. A stressed fish may darken, clamp fins, or lose contrast. Our photos show the intense natural patterning achieved through stable water, dark décor, and careful feeding rather than exaggerated editing. If you are researching red spotted severum wikipedia or hobby forums for visual references, note that line-bred strains can look very different from true notatus-type fish.

Sexing can be tricky. When people ask red spotted severum male or female, the answer is usually tentative until fish mature. Males may develop slightly longer finnage and more pointed dorsal or anal extensions, while females often appear rounder when mature. During pair formation, behaviour is often a better clue than colour alone.

Shoppers comparing spotted severum vs gold severum, spotted severum vs green severum, or spotted severum vs red head severum should think about whether they prefer a natural wild look or a brighter ornamental strain. The notatus fish is more subtle than a red spotted severum for sale line-bred fish, but many experienced keepers find it more elegant in a planted woodscape. It is also worth comparing spotted severum or blue acara if you want a South American cichlid with colour and personality but have slightly less space.

What Fish Can Live With Spotted Severum Cichlids? Compatibility Guide

This species is semi-aggressive rather than relentlessly hostile. In a roomy tank, a severum often coexists well with other medium to large peaceful or moderately assertive fish. That said, severum tank mates must be chosen with care. Tiny fish may be viewed as food, very aggressive cichlids can bully a severum, and hyperactive species can stress it. The best red spotted severum tank mates are fish that enjoy similar warm, soft water and can hold their own without constant conflict.

Ideal Tank Mates

Good options include angelfish, Geophagus species, larger peaceful tetras, and other calm South American cichlids of suitable size. Many hobbyists ask about spotted severum with angelfish. In a spacious tank, this can work very well because both species appreciate warm, softer water and a structured layout. Large characins can also add movement to the upper levels. If you want to compare cichlid personalities, the Lwanda Peacock Cichlid - Aulonocara Sp. is beautiful but comes from very different water chemistry, so it is not a true companion choice for a severum aquarium. Likewise, Malawi fish such as the Albino Golden Mbuna Cichlid - Melanochromis need harder, more alkaline water and should not share a tank with this species.

For larger display communities, open-water fish like the Waanders'S Hard-Lipped Barb may be considered only if water chemistry and temperament align, but South American companions are usually the safer route. Tanganyikan species such as Kitumba Jumbo Sardine Cichlid - Cyprichromis, Xenotilapia Ochrogenys «Kigoma» - Lake Tanganyika, and Yellow Sand Cichlid - Xenotilapia Bathyphilus are fascinating fish, yet they belong in a different style of setup with different mineral content.

Species to Avoid

Avoid very small tetras, shrimp, and delicate nano fish. This is not the fish for someone building a tiny tropical fish starter aquarium. It also should not be mixed with bettas, despite common searches like buy siamese fighting fish online uk or siamese fighting fish pets at home. Bettas need completely different social conditions and are too vulnerable. Likewise, novelty searches such as home aquarium sharks uk often lead beginners toward unsuitable mixes. Severums need thoughtful companions, not dramatic mismatches.

Community Tank Stocking Examples

In a 300-litre tank, keep one severum as the centrepiece with a small group of robust upper-level dithers. In 450 litres or more, a bonded pair can work with a group of larger tetras and a peaceful bottom-dweller group if filtration is strong. This is where the idea of a severum community tank becomes realistic. If you are searching tropical fish for sale online uk, live tropical fish for sale uk, or tropical fish uk for sale, plan your final stock list before ordering rather than adding fish one by one on impulse.

Species	Compatible?	Notes
Red Head Severum Cichlid - Heros	⚠️ Caution	Possible in very large tanks, but watch territorial disputes between similar cichlids.
Angelfish	✅ Yes	Often one of the best spotted severum compatible fish choices in warm, soft water.
Small tetra species	❌ Avoid	May be eaten once the severum matures.

People searching tropical fish for sale near me, tropical fish shop near me, tropical fish for sale glasgow, tropical fish for sale in uk, or tropical fish for sale in the uk often ask if this fish can go into a mixed community straight away. The answer is only if the tank is large enough and the stock list is compatible. It is also worth noting that this species is not a good option for rehoming situations linked to unwanted tropical fish or free tropical fish to good home unless you are fully prepared for adult size and lifespan.

How to Breed Spotted Severum Cichlids: Complete Breeding Guide

Spotted severum breeding is achievable in the home aquarium, but it is best described as moderate rather than easy. The biggest challenge is obtaining a compatible pair. Spotted severum pair bonding can be strong once established, but random adult pairings do not always succeed. The most reliable method is to grow a small group of juveniles together and allow a natural pair to form.

Breeding Setup

A dedicated breeding tank of 300 litres or more is ideal for a mature pair. Soft, clean water, warm temperatures around 26-28°C, and flat spawning surfaces such as slate, broad leaves, or smooth stones encourage spawning. If you are researching Heros notatus care with breeding in mind, water quality and low stress are the two biggest triggers. A calm tank with minimal disturbance often works better than constant intervention.

Spawning Behaviour

Before spawning, the pair usually cleans a chosen surface and becomes more territorial. This is when spotted severum breeding pair behaviour becomes obvious. The fish may lip-lock, shimmy, and circle one another. People often ask red spotted severum male or female during this stage, but the best clue is coordinated pair behaviour rather than appearance alone.

Egg Care & Hatching

Eggs are laid in rows on a cleaned surface and guarded by both parents. Depending on temperature, hatching usually occurs in about 2-4 days, followed by a wriggler stage before the fry become free swimming. Parents may move the fry to pits or sheltered areas. Young pairs sometimes eat the first few spawns, which is common and not always a sign of poor care.

Fry Care & Growth

Once free swimming, fry can be fed newly hatched brine shrimp, microworms, and finely crushed fry foods. Frequent small water changes are essential for growth. Because this is a Spotted Severum Cichlid rather than a tiny egg scatterer, fry numbers are manageable but still require planning. If you are used to keeping fish from tropical fish for sale online listings such as angelfish or discus, you will find severum fry care broadly similar in needing clean, stable water and frequent feeding.

Common Breeding Challenges

Common problems include incompatible pairs, egg fungus in poor water, and parental inexperience. Some aquarists compare this species with tropical discus fish for sale uk or discus tropical fish for sale uk when considering breeding projects. Severums are generally easier than discus but still reward patience. They are also a better fit for many keepers than more demanding oddballs such as tropical puffer fish for sale uk.

Spotted Severum vs Similar Species: Which Should You Choose?

Comparison matters because severums are often sold under overlapping common names. A buyer looking for a Red Spotted Severum, red spotted severum for sale UK, or super red severum fish for sale may actually be choosing between very different fish in terms of colour emphasis, rarity, and overall look. The Spotted Severum is usually chosen for natural patterning and a more wild-style appearance.

If you are weighing Heros notatus vs rotkeil severum, choose notatus when you want a more authentic, understated fish for a blackwater-inspired aquarium. Choose Rotkeil or red head forms if you prefer stronger ornamental colour. If you are debating spotted severum or blue acara, the acara is easier in smaller tanks, but the severum has more imposing presence. For aquarists interested in large tropical fish for sale uk, unusual tropical fish for sale uk, or exotic tropical fish for sale uk, the Spotted Severum offers a satisfying middle ground: impressive, intelligent, but not excessively difficult.

It is also a better fit for many homes than fish often searched under tropical fish tank for sale uk packages, where tank size is underestimated. This species deserves a properly scaled setup from the start. If you want to compare directly with related fish, view the Red Head Severum Cichlid - Heros and Heros Sp. Rotkeil - Redneck Severum.

Common Health Problems in Spotted Severum Cichlids & How to Prevent Them

A healthy severum is alert, responsive, thick-bodied without bloating, and shows smooth finnage with clear eyes. Appetite should be strong but not frantic. Because this species comes from softer, more acidic water, poor severum water conditions are behind many health problems. The most common issues are stress darkening, hole-in-the-head linked to poor diet and water quality, bacterial infections after fighting, and external parasites introduced by new fish.

Signs of a Healthy Fish

Look for steady swimming in the middle levels, interest in food, and calm interaction with the environment. A healthy red spotted severum full grown specimen should have good body depth, no pinched belly, and no frayed fin edges. Pattern should appear clear rather than muddy or washed out.

Common Diseases & Symptoms

White spot can appear after transport stress or sudden temperature drops. Hole-in-the-head can develop over time if diet lacks vegetable matter and water quality is poor. Bloating may follow overfeeding or constipation from an overly rich diet. If you keep this fish in water outside the recommended severum pH level and hardness range for long periods, chronic stress becomes more likely.

Treatment Options

First correct the environment: test water, increase water changes, and check filtration. Quarantine the fish if needed. Use species-appropriate medications carefully and avoid mixing treatments without diagnosis. Although severums are robust, they do not respond well to guesswork. Good husbandry solves many issues faster than repeatedly adding medication.

Prevention Tips

Maintain stable severum water parameters, feed a varied omnivorous diet, and avoid overcrowding. Quarantine all new arrivals. This matters especially if you regularly buy fish online or add fish from multiple sources. A fish that looks fine in a sales tank can still carry parasites. If you have read aquatics to your door reviews or other delivery-based fish feedback online, you will notice that the best outcomes nearly always come from careful acclimation and quarantine, not rushed stocking.

Understanding Spotted Severum Behavior in the Aquarium

Spotted severum behaviour is one of the reasons this fish is so popular. It is observant, often learns feeding routines quickly, and tends to watch activity outside the tank. Most individuals spend their time cruising the middle levels, inspecting wood and plants, and gently asserting themselves without the nonstop aggression seen in some other cichlids.

This fish is best kept singly or as a bonded pair. A lone specimen often becomes a calm centrepiece, while a pair shows more interactive behaviour and can display fascinating courtship rituals. In cramped tanks, however, even a usually peaceful severum can become territorial. That is why a proper spotted severum care guide always places layout and space ahead of chasing colour morphs.

Natural behaviour is easiest to see in a structured setup with sight breaks, warm soft water, and a predictable routine. If the tank is too bright, too busy, or stocked with incompatible fish, the severum may hide, darken, or become defensive. In a suitable aquarium, it shows exactly the graceful movement and calm authority that make it such a standout red spotted cichlid for large tank option.

Why Buy from Tropical Fish Co?

When you order a severum, the quality of early care matters. This species often arrives as a juvenile, and the difference between a well-started fish and a poorly handled one becomes obvious months later in growth rate, confidence, and finnage. Our Spotted Severums are selected for body shape, alert behaviour, and clean patterning rather than simply listed as another generic tropical fish for sale UK item. That matters with Heros notatus, where natural pattern and condition are part of the appeal.

Each fish is observed before dispatch, and we only send specimens that are feeding properly and showing stable behaviour. For customers searching Heros UK, severum UK, buy live fish online uk free delivery, best place to buy tropical fish online, or best place to buy tropical fish online uk, confidence comes from preparation, not marketing claims. Fish are packed in insulated boxes, with heat packs in cold weather, and sent by tracked service suitable for live fish transport. This helps maintain temperature stability during tropical fish for sale uk delivery orders.

We also know many buyers are comparing this fish with chain-store options under searches like fish for sale pets at home or tropical fish pets at home. The difference with a species like this is guidance. A severum is not a throw-in purchase for a random freshwater fish bundle. It needs a mature tank, compatible stock, and realistic planning for adult size. If you want to buy fish online with a clear idea of what this species needs, this is the kind of fish worth buying carefully rather than casually.

Whether you are looking for red spotted severum for sale, spotted severum for sale UK, spotted severum online UK, spotted severum shop UK, or checking Heros notatus price UK, order your fish when the tank is ready, not before. That is the best way to enjoy a healthy, settled severum for years.
