The Blackbelt Cichlid (Vieja maculicauda) 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 75-82°F, and a pH of 7-8.
Captive lifespan reflects typical experience in a home aquarium, not maximum recorded age; genetics, sourcing, and care vary.

Blackbelt 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 75-82°F and a pH around 7-8. They grow to around 32 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 Blackbelt 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.
Blackbelt Cichlid Tank Mates
Robust, adaptable Central American river cichlid - far more tolerant of varied water chemistry than Rift Lake species, but grows large and needs a correspondingly large tank. Territorial and increasingly aggressive with size and age; best kept singly or as an established pair. The Blackbelt 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 Blackbelt 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.
Blackbelt Cichlid - frequently asked questions
What size tank do Blackbelt Cichlids need?
Blackbelt 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 Blackbelt Cichlids need?
Keep them at 75-82°F with a pH of 7-8, 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 Blackbelt Cichlids eat?
Blackbelt 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 Blackbelt Cichlids good for beginners?
Blackbelt 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 Blackbelt 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 - Blackbelt Cichlids will nip at bettas, angelfish, and other fish with flowing fins, causing stress and infection risk.
