Arnold's / Five Spot Cichlid (Thysochromis ansorgii)

Overview

Arnold's / Five Spot Cichlid is a characterful West African cichlid often traded under the supplier label Thysia ansorgei. The accepted scientific name to plan around is Thysochromis ansorgii, so both names are included here for clarity. It is a pair-bonding, cave-spawning fish from West African coastal river systems, not a South American cichlid and not a tiny nano species.

This product covers three size options: 4-5 cm, 5-7 cm and >8 cm. The smaller option is the sale size, not the final care size. FishBase records 8.8 cm standard length and also notes a 12-13 cm total-length record, so the safe aquarium plan is for a medium, territorial cichlid with enough footprint, structure and escape routes.

Appearance

Five Spot Cichlids have a refined West African look rather than the high-contrast colour of many lake cichlids. Expect a laterally compressed body, pale gold to olive body colour, blue-green iridescence on the face and scales, and dark flank markings that give the fish its common name. Mature fish can show a stronger blue sheen across the head and flanks, while the dorsal, anal and caudal fins may display spotting, edging and reddish or yellowish warmth depending on mood, sex and condition.

The existing four gallery images are being preserved because they already give shoppers useful views of shape and aquarium context. The exact Petra source image for SKU 0990 is also being added as an extra reference image, not as a replacement, so the page keeps both the old visual depth and the supplier trace.

Natural Habitat

Thysochromis ansorgii is a freshwater, demersal cichlid from West African coastal basins. FishBase lists records from Ivory Coast river systems including Agnebi, Me, Bia, Comoe and Tano, then east through forested coastal lowlands in Nigeria including the Ogun, Oshun, Niger delta, Ethiop, Calabar, Great Kwa and lower Cross, with Benin's Oueme included and a report from Gabon's Ogowe basin. That is a very different husbandry context from the old South American metafield.

In practical aquarium terms, think warm, planted or wood/rock structured freshwater with subdued spaces, cave entrances and broken sight lines. The species is not a blackwater-only specialist, but it does need clean, stable water and cover. It should feel able to hold a territory without being forced into constant face-to-face conflict.

Aquarium Setup

Use at least 120 litres for an adult pair, and choose a larger aquarium if you want other cichlids or active mid-water fish in the same system. Footprint matters. A 90 cm or larger tank length gives the pair room to choose a cave and makes it easier to create visual breaks. The previous 60-litre guidance was too optimistic once the >8 cm sibling variant and recorded adult size are considered.

Build the layout with smooth rock, wood, caves, coconut shells, terracotta caves or other aquarium-safe shelters. Add sand or fine gravel, then place several cave-like structures so the fish are not forced to share one entrance. Hardy plants such as Anubias, Java fern and Cryptocoryne can work if protected from digging. Floating plants or shaded areas help shy fish settle, and a mature filter with good oxygenation keeps the territory clean.

Water Parameters

FishBase gives a source range of pH 6.0-8.0, hardness 5-19 dH and 24-26C. Keep those numbers stable rather than chasing the edge of the range. For most UK aquariums, aim for neutral to slightly acidic or neutral to mildly alkaline water, moderate mineral content and a reliable temperature around 24-26C. Avoid sudden pH or hardness swings when using tap-water mixes, RO water or botanicals.

As with many cichlids, water quality is the difference between a confident fish and a stressed fish. Keep ammonia and nitrite at zero, manage nitrate with routine partial water changes and avoid heavy feeding in a cave-filled tank where leftovers can disappear behind decor. New arrivals should be acclimated slowly, with lights low and the tank already cycled.

Feeding

Use a varied omnivorous cichlid diet. A quality small cichlid pellet or granule can be the staple, with spirulina or vegetable-rich foods included regularly. Supplement with frozen or live foods such as brine shrimp, daphnia, cyclops, mysis and occasional bloodworm. The goal is steady condition and breeding readiness, not over-rich feeding.

Feed small portions once or twice daily and watch where the food lands. Territorial cichlids often prefer to feed near cover, but uneaten food trapped in caves will quickly damage water quality. If tank mates are present, make sure this fish is not either bullying all food away or being pushed back from it.

Behaviour and Compatibility

This is a territorial but rewarding cichlid. FishBase describes it as a pair-bonding substrate brooder that spawns preferentially in caves or cave-like structures. A settled pair can patrol together, defend a chosen shelter and show excellent parental care. Outside breeding, well-kept fish can be calmer than the word cichlid sometimes suggests, but spawning mode can change the atmosphere quickly.

Good tank mates are robust fish that enjoy similar water and do not compete for exactly the same cave. In larger West African-style aquariums, possible companions include calm African tetras, suitable rainbowfish in harder neutral water, Synodontis or other robust catfish where size is appropriate, and other African cichlids only when the footprint and territories are planned. Avoid tiny fish, shrimp, very delicate species, slow long-finned fish, aggressive bruisers, and cramped mixes of cave-spawning cichlids.

Breeding

Thysochromis ansorgii is best treated as a cave-spawning substrate brooder. Provide several tight shelters and let the pair choose. The female is likely to spend more time close to eggs and fry, while the male patrols the surrounding territory. Do not keep the pair in a busy community if breeding is the aim, because stress can lead to failed spawns, egg loss or aggression toward tank mates.

Clean water, a varied diet and quiet cover matter more than tricks. Fry are usually able to take tiny live foods such as newly hatched brine shrimp once free-swimming, with fine prepared fry foods used carefully as a backup. If you are raising fry intentionally, plan a separate grow-out tank and be ready to move young fish before territory pressure builds.

Health and Acclimation

Prepare the aquarium before delivery day. The tank should be fully cycled, heated, filtered and already close to the target water chemistry. On arrival, keep the lights low, float the sealed bag to equalise temperature, then add small amounts of aquarium water gradually before release. Do not pour transport water into the display tank.

Watch the first week carefully. A healthy Five Spot Cichlid should hold itself upright, breathe steadily, investigate cover and begin feeding once settled. Hiding at first is normal for a new cave cichlid, but persistent rapid breathing, clamped fins, refusal to leave the surface, bullying or visible damage should trigger a water test and a review of tank mates. Quarantine is recommended where practical, especially if the fish will join a valuable established cichlid group.

Who This Fish Is Best For

Choose this fish if you want a less common West African cichlid with real behaviour, pair dynamics and a natural cave-territory lifestyle. It suits keepers who can provide a mature aquarium, stable water, structured decor and thoughtful tank mates. It is not the best choice for a tiny first aquarium, a delicate soft-water community, or a peaceful display where every fish must ignore every other fish.

It is also a useful choice for aquarists who enjoy the less common West African cichlid group rather than only the familiar lake species. The appeal is in the natural behaviour: cave selection, pair interaction, confident feeding and territorial displays that make the aquarium feel alive.
