Papiliochromis ramirezi electric blue gold head

Meet the Electric Blue Gold Head Ram

The Electric Blue Gold Head Ram (Papiliochromis ramirezi) is a small freshwater cichlid from the Orinoco River basin in the llanos of Venezuela and Colombia. It reaches a recorded maximum of 4.2 cm standard length and suits a keeper who can maintain consistently warm, clean, soft and acidic water. This ornamental ram combines an iridescent electric-blue body with a golden head while retaining the compact shape and bottom-oriented feeding behaviour associated with the species.

FishBase records the species in the family Cichlidae and gives 4.2 cm standard length as its maximum recorded size. FishBase now lists it as Mikrogeophagus ramirezi. The name Papiliochromis ramirezi remains the scientific name used for this colour form here, while Electric Blue Gold Head Ram is the useful aquarium trade name.

Use the overlap of the Seriously Fish aquarium values and FishBase’s recorded environmental range: 27–30°C, pH 5.0–6.0 and 5–10 dGH. Provide excellent biological filtration and a base measuring at least 60 × 30 cm for a pair. A practical pair aquarium should hold at least 60 litres; use at least 80 litres when planning a carefully screened mixed aquarium. Tank mates must tolerate the same warmth and acidity without competing aggressively for food.

Choose this ram when you want a small South American cichlid whose needs can shape the aquarium. It works best as the focal fish in a structured layout rather than as an afterthought in a busy collection. You can also browse our South American cichlid collection when comparing animals with different space, social and water requirements.

Choose the dispatch size separately from adult planning

One purchase supplies one fish in the size selected. Use the live size selector to choose between the labels 3 - 3,5 cm, 3,5 - 4 cm and 4-6 cm. These labels describe the dispatch grade and should be used when deciding which fish best fits your immediate stocking plan.

The size you select is the size supplied, not the adult size. Plan the permanent aquarium around the recorded 4.2 cm standard length, the space needed by a pair and the territorial behaviour that may develop as the fish settle. Do not use a smaller dispatch grade as a reason to reduce the aquarium footprint or postpone filtration and cover.

Sex is guaranteed only when the selected option explicitly states male or female. This Papiliochromis ramirezi electric blue gold head listing has no sex-guaranteed option.

The gallery images are representative of this type of animal rather than photographs of the exact animal supplied, so colours can look slightly different from the live animal.

Use the visible colour pattern to understand the named form, not to predict the exact shade, markings or sex of an individual fish. The aquarium, diet, stress level and individual variation can all affect how a fish presents after a move, so judge its early progress through breathing, swimming, feeding and condition as well as colour.

Decide whether this ram fits your aquarium

This ram fits an aquarium built around high water quality, a warm temperature and restrained stocking. The decisive question is not whether the fish is physically small enough to enter the tank; it is whether the aquarium can remain stable at 27–30°C while giving a pair a 60 × 30 cm base, cover and reliable access to food.

Its small adult size does not make it carefree. Seriously Fish describes the species as requiring pristine water quality and being a poor competitor, while OATA notes that dwarf cichlids may become territorial, especially when breeding. Success therefore comes from combining clean water, suitable structure and conservative companion choices rather than relying on the word “dwarf”.

Hold a warm, soft and acidic water range

Keep the aquarium at 27–30°C, pH 5.0–6.0 and 5–10 dGH. These routine targets sit within both the aquarium values published by Seriously Fish and the recorded environmental ranges given by FishBase. Seriously Fish gives 27–30°C, pH 4.0–7.0 and 1–10 dGH; FishBase records 27–30°C, pH 5.0–6.0 and 5–12 dH. Using their overlap avoids pushing the aquarium beyond either set of values.

OATA’s dwarf-cichlid guidance gives 22–27°C, pH 6.0–8.0 and 4–12 dH for the wider group. This ram requires the warmer end and a more acidic target, so set the aquarium for the species rather than applying the full dwarf-cichlid range.

Control stability as well as the reading

• Temperature: choose equipment that can hold 27–30°C steadily in the actual room conditions.
• pH: use 5.0–6.0 as the routine target and avoid abrupt attempts to chase a single decimal reading.
• Hardness: keep general hardness between 5 and 10 dGH.
• Waste: maintain ammonia and nitrite at zero; OATA advises nitrate should not exceed 20 mg per litre above the normal tap-water level.

Measure the aquarium before choosing livestock, then compare the results with the target. Our water chemistry guide explains what the main tests mean, while the water matcher helps compare measured values with this range. Record results over time: a stable pattern is more useful than one isolated test taken immediately after maintenance.

Plan the aquarium around a pair

Give a pair a base measuring at least 60 × 30 cm. Seriously Fish describes that footprint, approximately 54 litres, as sufficient for a single pair. For practical planning, use an aquarium of at least 60 litres; OATA also recommends at least 60 litres for a pair of dwarf cichlids and at least 80 litres when they are mixed with other fish.

Footprint matters because these fish feed around the substrate and need separate areas of cover. Extra height does not replace usable floor area, caves, shaded places and clear routes between them. In a mixed aquarium, added volume is valuable only when the layout also prevents one fish from controlling every shelter and feeding point.

Build a useful lower level

• Use a soft sandy substrate to support the natural mouthful-and-sift feeding action described for Mikrogeophagus.
• Arrange wood roots or branches to form shaded places and visual barriers.
• Add caves using suitable pots, pipe sections or aquarium ornaments.
• Include one or two flat rocks or similar firm surfaces.
• Use live or artificial plants to increase cover without blocking the whole base.
• Leave open patches where food can be seen and reached before faster fish take it.

Seriously Fish notes that the species is flexible about décor when adequate cover and structure are present. A natural-looking arrangement may combine sand, wood, leaf litter, plants, shade and caves, but the functional goal is more important than copying a particular style. Each fish should be able to leave the other’s sight and reach shelter without crossing a single exposed route.

Before committing to companions, sketch the floor plan rather than considering litres alone. In a 60 × 30 cm pair aquarium, place retreats towards different ends and preserve a central feeding area. In an aquarium of at least 80 litres, use plants or wood to divide the base into several visible zones instead of creating one uninterrupted territory.

Mature the filter before adding the fish

Use a fully established biological filter and add this ram only after ammonia and nitrite test at zero. The RSPCA explains that biological filtration supports bacteria that convert toxic ammonia first into nitrite and then into the safer nitrate. A filter is therefore essential even when the aquarium looks clean.

Seriously Fish suggests gentle movement and, for an aquarium around 54 litres, a filter rated at approximately 110–160 litres per hour. Treat that flow as a starting point for the stated tank size: the useful result is steady filtration without turning the lower part of the aquarium into a high-current channel. Position the outlet so water circulates through the tank while sheltered areas remain usable.

Prepare before the fish arrives

1. Set up the substrate, cover, heater and filter before livestock.
2. Allow the biological filter to mature and confirm its progress with water tests.
3. Check that temperature remains within 27–30°C throughout the day.
4. Confirm pH 5.0–6.0 and general hardness 5–10 dGH.
5. Test ammonia and nitrite and proceed only when both read zero.
6. Add fish gradually so the bacterial population can adjust to increased waste and feeding.

Our first tropical aquarium guide covers the preparation and maturation sequence in more detail. Do not treat clear water as proof that the filter is ready; ammonia and nitrite are dissolved and require tests.

OATA warns that stocking too quickly can cause new tank syndrome when the bacterial population cannot process the increased waste. This species is particularly poorly suited to that risk because Seriously Fish describes it as needing pristine water quality. Start with conservative stocking, feed carefully and test after any increase in the aquarium’s biological load.

Feed for bottom-sifting behaviour

Offer a varied diet led by small live and frozen foods such as bloodworm, Artemia, Daphnia and grindal worm, with good-quality sinking dried food of a suitably small size as a supplement. Seriously Fish describes Mikrogeophagus as benthophagous: it takes mouthfuls of substrate, sifts out edible items and expels the remaining material through the mouth and gill openings. It may also browse solid surfaces or take food from the water column.

Feed once a day and give only what the fish can finish within a few minutes. That portion and schedule follow OATA’s dwarf-cichlid guidance. Remove or reduce food when pieces remain after the feeding period, because uneaten food decomposes and adds waste to an aquarium whose water quality must remain exceptionally clean.

Make sure the ram actually eats

• Place suitably small food where it can reach the lower part of the aquarium.
• Watch the fish take food rather than judging the portion only by what disappears.
• Use several small feeding points when a companion repeatedly takes the first share.
• Vary live, frozen and sinking prepared foods instead of relying on one product.
• Reduce the next portion if food remains on the substrate after a few minutes.

A gelatine-bound food containing mixed dried fish food, puréed shellfish, fruit and vegetables is another form described by Seriously Fish, provided it is cut into bite-sized pieces. The practical test is whether the ram can find, take and swallow the food without having to compete with faster or more forceful fish.

Poor feeding access can look like fussiness when the real problem is competition. If a ram hangs back while open-water fish clear the meal, adjust placement and companion stocking before simply increasing the total amount. Adding more food without checking who eats it can leave the ram underfed while raising ammonia, nitrite or nitrate through excess waste.

Use a repeatable weekly maintenance routine

Change 25% of the water at least once every week, treating replacement tap water with conditioner before it enters the aquarium. OATA recommends this schedule for dwarf cichlids and advises regular testing at least weekly. Match replacement water carefully enough to avoid abrupt changes to the established 27–30°C, pH 5.0–6.0 and 5–10 dGH conditions.

Weekly checklist

1. Observe breathing, swimming, colour, feeding and interactions before disturbing the tank.
2. Test ammonia and nitrite, which should remain at zero.
3. Check nitrate against the normal tap-water baseline.
4. Siphon visible solid waste while removing approximately 25% of the aquarium water.
5. Treat replacement water for chlorine or chloramine before adding it.
6. Check the filter intake and outlet for blockages or reduced flow.
7. Record the results so gradual changes become visible.

When filter media needs cleaning, rinse it lightly in aquarium water removed during the partial change. Rinse filter media in water removed from the aquarium, never under the tap, because chlorine or chloramine may damage the beneficial bacteria living in the media. Avoid replacing every piece of biological media together unless the equipment instructions make that unavoidable.

Separate routine maintenance from emergency over-correction. If pH or hardness begins moving away from the target, first repeat the test, check the tap-water baseline and review recent changes to water, décor or maintenance. Sudden chemical adjustments can create a sharper swing than the original reading.

The first-month pattern should be simple: test at least weekly, change 25%, check the filter and review whether every fish is eating. Test more frequently after adding livestock, changing feeding substantially or seeing abnormal behaviour. The aim is not merely a clean-looking aquarium but a stable biological system in which waste is processed and changes are detected before they affect the fish.

Follow the arrival and introduction sequence

Arrange for someone to receive the parcel because live fish must not be left unattended. Tropical Fish Co hand-bags fish in oxygen, uses an insulated box and adds a heat pack when the weather calls for one. A licensed live-animal courier carries the parcel, with tracking and the delivery date communicated by email.

Before introduction, use the overlap of the Seriously Fish aquarium values and FishBase’s recorded environmental range to confirm 27–30°C, pH 5.0–6.0 and 5–10 dGH. OATA advises checking that ammonia and nitrite are zero before adding fish.

Follow the delivery-policy steps

1. Make sure someone is present to receive the parcel.
2. Start filming while the parcel is still sealed. Make one continuous short unboxing video showing the sealed parcel, the parcel being opened and the fish still inside the bag.
3. Float the bag for 20–30 minutes before releasing the fish.
4. Release the fish after that acclimatisation period.
5. Never pour the bag water into the aquarium.

These steps come from our delivery and Live Arrival Guarantee policy. Read the current policy before the delivery window so the receiver knows the unpacking, evidence and acclimatisation requirements.

After introduction, OATA advises checking that a new fish shows clear, bright eyes, intact scales and fins, appropriate swimming and a normal interest in food. Some initial caution is understandable in a covered aquarium, but the direction of travel should be towards controlled swimming, steady breathing and reliable feeding.

Increase stocking slowly after the fish has settled. Every additional fish and every increase in feeding raises the waste load handled by the biological filter. Test ammonia and nitrite following an addition rather than assuming the established filter will adapt immediately.

Before arrival day, complete a final practical check: the heater holds the target temperature, the filter has steady flow, caves remain accessible, and food is small enough for this fish. This preparation removes avoidable decisions from the first few hours and lets observation focus on the animal’s condition and behaviour.

Track growth, condition and behaviour together

Plan around a maximum recorded adult size of 4.2 cm standard length. FishBase gives that figure, while Seriously Fish gives 4.0 cm standard length. Use 4.2 cm consistently for adult planning and remember that a small body still needs a full territorial footprint, clean water and reliable feeding access.

FishBase describes aquarium keeping in pairs, and Seriously Fish considers a 60 × 30 cm base sufficient for a single pair. Juveniles are described as gregarious, but the long-term plan should not assume that several adults will remain comfortable within a pair-sized aquarium. Use extra space, structure and active observation whenever more than one territorial area may develop.

Healthy progress to look for

• Steady swimming without hanging at the surface or sitting abnormally on the bottom.
• Regular interest in appropriately sized food.
• Stable body condition rather than a gradual loss or increase in weight.
• Gill covers moving at a consistent rate.
• Fins, scales and skin remaining intact.
• Use of cover without a persistent inability to leave it and feed.

OATA advises watching for changes in swimming, colour, temperament, breathing, appearance, condition and feeding. If breathing becomes unusually fast or slow, feeding drops, aggression changes sharply, or white spots, fluffy growths, damaged fins or ulcers appear, test the water first and contact us for health guidance. Avoid choosing a treatment before checking temperature, ammonia, nitrite, nitrate trend, pH and recent maintenance.

Behaviour must be read in context. A fish using a cave can be making normal use of the layout; a fish confined there by repeated chasing requires action. Likewise, colour alone is a poor first-week measure. Combine it with feeding, respiration, posture, swimming and access to space before deciding whether the fish is settling successfully.

Screen every companion for water, temperament and feeding

Choose peaceful open-water fish that tolerate 27–30°C, pH 5.0–6.0 and 5–10 dGH without dominating food. Seriously Fish particularly recommends groups of peaceful open water-dwelling characids or similar fish because their presence may reduce shyness. It names Paracheirodon axelrodi and Paracheirodon simulans as examples able to manage the required warmth.

Avoid territorial or otherwise aggressive fish, including most other cichlids, and avoid species that require harder water. A fish cannot be a suitable companion merely because it is peaceful at a different temperature or chemistry. It must fit all three tests: shared water values, restrained behaviour and fair access to food.

Use this screening order

1. Water: can the proposed companion live long term at 27–30°C, pH 5.0–6.0 and 5–10 dGH?
2. Space: does an aquarium of at least 80 litres provide enough usable area and cover for the mixed stocking plan?
3. Temperament: is the companion peaceful and non-territorial around the lower level?
4. Feeding: will the ram receive small live, frozen and sinking foods before faster fish clear them?
5. Response: can you separate fish if chasing, exclusion or poor feeding develops?

Very active or boisterous fish require caution because this ram is described as a poor competitor. For fish or invertebrates not named here, judge the combination against water, space, feeding and behaviour rather than relying on a universal compatibility label. Outcomes may depend on the aquarium layout and individual animals. Ask us for a stocking assessment with the tank dimensions, measured water values and complete livestock list.

Manage territory with layout and observation

Treat territorial behaviour as a normal possibility, especially around breeding. OATA notes that dwarf cichlids may become territorial and that even settled pairs will often chase each other. Cover is therefore not decorative excess: it gives a pursued fish somewhere to withdraw and interrupts direct lines of sight.

In a pair aquarium, provide more than one shelter and arrange them so one fish cannot watch every entrance from a single position. In a mixed aquarium, start with at least 80 litres and divide the lower area with plants, wood and caves. Keep open feeding patches within reach of more than one retreat.

Do not wait for physical damage before acting. Repeated exclusion from food or shelter is already a husbandry problem. Check whether both fish can move around the aquarium, eat and rest without continuous pursuit.

Compatibility remains conditional throughout the fish’s life. A combination that appears calm at first may change as territories form. Keep the layout adjustable, observe interactions during feeding and retain a practical separation plan. The safest community is one built around this ram’s warm, soft, acidic water and low tolerance for aggressive competition.

Answers to common buyer questions

How big does Papiliochromis ramirezi electric blue gold head get?

The Electric Blue Gold Head Ram reaches a recorded maximum of 4.2 cm standard length. Plan its aquarium around that adult figure, not the selected dispatch size.

What size aquarium does Papiliochromis ramirezi electric blue gold head need?

Seriously Fish gives a 60 × 30 cm base, approximately 54 litres, as sufficient for one pair. For practical planning, use at least 60 litres for a pair; OATA’s dwarf-cichlid guidance An aquarium of at least 80 litres is required when mixing them with other fish.

How many Papiliochromis ramirezi electric blue gold head fish should I keep together?

Keep them as a pair. FishBase describes aquarium keeping in pairs, and Seriously Fish bases its 60 × 30 cm aquarium recommendation on a single pair.

Is Papiliochromis ramirezi electric blue gold head suitable for beginners?

It suits a keeper who can maintain pristine water at 27–30°C, pH 5.0–6.0 and 5–10 dGH, test weekly and protect a poor competitor’s access to food. It is a demanding choice for a new or unstable aquarium.

What does this fish eat?

Feed small live and frozen foods such as bloodworm, Artemia, Daphnia and grindal worm, supplemented with suitably small sinking dried food. Offer only what it can finish within a few minutes, once a day.

What temperature and pH does Papiliochromis ramirezi electric blue gold head need?

Keep this ram at 27–30°C and pH 5.0–6.0, with general hardness of 5–10 dGH. These values overlap the Seriously Fish aquarium range and FishBase’s recorded environmental range.

Is it aggressive or likely to nip fins?

It may become territorial, especially when breeding, so provide several shelters and visual barriers. Screen companions for aggression, territory, water requirements and feeding competition, and act if one fish is repeatedly chased or excluded.

Which kinds of fish can it live with?

Choose peaceful open water-dwelling characids or similar fish that tolerate 27–30°C and soft, acidic water; Seriously Fish names Paracheirodon axelrodi and Paracheirodon simulans. Avoid territorial or aggressive fish, most other cichlids and fish requiring harder water.
