Blue Dolphin Cichlid
Cichlidae sp.
The Blue Dolphin Cichlid (Cichlidae sp.) is an aggressive fish that's best left to experienced keepers. Give it a tank of at least 250 litres (66 US gallons), water held at 77-84°F, and a pH of 6.5-8.5.
Captive lifespan reflects typical experience in a home aquarium, not maximum recorded age; genetics, sourcing, and care vary.

Blue Dolphin Cichlid Tank Setup
Give them at least 250 litres (66 US gallons). Cichlids are territorial and produce plenty of waste, so strong filtration and some rocks or wood to break up sight lines both help. Aim for 77-84°F and a pH around 6.5-8.5. They grow to around 25 cm, so plan the tank size and filtration for a full-grown adult rather than the small juvenile you see in the shop.
What Do Blue Dolphin Cichlids Eat?
They're not fussy eaters - feed a varied diet, rotating good-quality dry, frozen, and gel foods rather than the same thing every day, and match the food size to their mouths.
Blue Dolphin Cichlid Tank Mates
May nip fins; avoid with long-finned or slow tankmates. Predatory; may eat small fish or inverts. Requires a large tank and good filtration. The Blue Dolphin Cichlid is aggressive, which is the first thing to weigh up when you choose tank mates. It's a known fin-nipper, so avoid bettas, guppies, and other slow, long-finned fish. It's predatory, so anything small enough to fit in its mouth will be treated as food rather than a companion. Before you buy, run your full stocking list through our stocking calculator. It weighs temperament, adult size, and water needs together, which a single species page can't do on its own.
Are Blue Dolphin Cichlids Good for Beginners?
Not a sensible first purchase. Get the tank cycled, keep easier fish stable for a year, then revisit if you still want the extra work this species demands.
Blue Dolphin Cichlid - frequently asked questions
What size tank do Blue Dolphin Cichlids need?
Blue Dolphin Cichlids need a tank of at least 250 litres (66 US gallons). A bigger tank is always easier to keep stable, and gives them more room to settle in and behave naturally.
What water parameters do Blue Dolphin Cichlids need?
Keep them at 77-84°F with a pH of 6.5-8.5, steady rather than chased to an exact figure. In a cycled tank, ammonia and nitrite should both read 0 ppm, with nitrate kept low through regular water changes.
What do Blue Dolphin Cichlids eat?
Blue Dolphin Cichlids are omnivores and aren't fussy eaters. Feed a varied mix of good-quality dry, frozen, and gel foods, and match the food size to their mouths. Feed small amounts once or twice a day, and remove anything they don't eat.
Are Blue Dolphin Cichlids good for beginners?
Blue Dolphin Cichlids are not a beginner species. They need precise conditions and consistent maintenance, so build experience with hardier fish before keeping them.
Common mistakes with Blue Dolphin Cichlids
- Underestimating tank size - the minimum footprint is 250 litres (66 US gallons); impulse buying into a smaller tank leads to stress and shortened lifespan.
- Mixing with long-finned fish - Blue Dolphin Cichlids will nip at bettas, angelfish, and other fish with flowing fins, causing stress and infection risk.

Great tank mates
Chosen from temperament, overlapping temperature/pH bands, plausible minimum tank footprints, and size versus yours in App-aquatic data. Hobby nuance always wins - verify stocking and temperament before purchasing.
