Appearance

Displays extraordinary coloration with males showing electric blue body overlaid with golden-yellow markings and intense red finnage creating marine-like beauty. Among most spectacularly colored freshwater fish available. The 12 cm size creates commanding presence for killifish. Females more subdued but attractive. Breeding males intensify colors dramatically. The "Blue Gularis" and "Golden Pheasant" common names reference spectacular appearance.

Natural Habitat

Inhabits Niger Delta freshwater systems in Nigeria and Cameroon. Soft acidic water (pH 6.0-7.5), warm temperatures (22-26°C), vegetated slow-moving waters. Occupies areas with dense cover where spectacular coloration provides camouflage among vegetation and dappled light. The substantial size means can exploit larger prey than smaller killifish.

Aquarium Setup

75-litre minimum for pairs reflecting larger size. Create well-planted aquarium with dense vegetation providing security and territorial boundaries. Floating plants create subdued lighting. Fine-leaved plants for spawning. Gentle filtration avoiding strong current. Dark substrate enhances spectacular coloration through contrast. Tight-fitting secure cover essential—powerful jumpers requiring weighted lids. Provide hiding places reducing aggression.

Water Parameters

Soft slightly acidic water essential. pH 6.0-7.5, soft water (2-10 dGH), temperatures 22-26°C. Use RO water or peat filtration achieving soft conditions. Weekly 30% water changes with aged water. Stability critical. Ammonia/nitrite 0 ppm, nitrates below 30 mg/L. Pristine quality essential for maintaining spectacular coloration and breeding success.

Feeding

Dedicated carnivore with substantial appetite reflecting 12 cm size. High-quality live/frozen bloodworms, brine shrimp, daphnia, mosquito larvae, small carnivore pellets. The larger size means can accept more substantial foods than smaller killifish. Feed once-twice daily in portions consumed within minutes. Varied carnivorous diet improves color and breeding condition.

Behaviour

Semi-aggressive with territorial behavior particularly from males. Can be kept in pairs or small groups in spacious aquariums with extensive cover. Males display spectacular colors defending territories and courting females. More assertive than smaller killifish reflecting larger size. Best species-only or with carefully selected peaceful similarly-sized tankmates in larger aquariums. Fascinating to observe when provided appropriate conditions.

Tank Mates

Best species-only or very peaceful similarly-sized tankmates in larger aquariums. Avoid small fish (eaten/outcompeted), active bottom dwellers (stress), fin-nippers, large aggressive cichlids, fast boisterous community fish, very small fry/shrimp (predation), other aggressive killifish. Careful planning essential for any community arrangements.

Breeding

Breeds in soft acidic water with fine-leaved plants/spawning mops. Eggs laid among plants/substrate requiring careful incubation depending on line/setup. Fry substantial size for killifish, accepting baby brine shrimp immediately after free-swimming. Remove adults protecting eggs. Breeding achievable with proper conditions though less prolific than smaller annual killifish.
