Overview
Apistogramma are small cichlids from the warm, tea-colored rivers of the Amazon in South America. There are dozens of different kinds, and the males are usually the show-offs, flashing bright fins in blue, orange, red, and yellow to impress the females and warn off rivals. Even though they are only a couple of inches long, they behave like much bigger cichlids, exploring every corner of their tank and claiming a favorite cave as home.
Fishkeepers love them because they are smart and full of character. They recognize their owners, tilt their heads to watch you, and put on amazing displays. They do best in soft, slightly acidic water with plenty of hiding spots, which reminds them of the leaf-covered streams where they come from.

Water and tank
Apistogramma come from soft, acidic Amazon streams, so they are happiest in water that is warm and gentle rather than hard. A tank of about 20 gallons gives a pair enough space to claim a territory. Adding dried leaves like Indian almond leaves stains the water a soft brown color, releases helpful tannins, and makes these fish feel safe and at home.
Aquascape and setup
These fish love a tank with lots of cover. Coconut hut caves, smooth stones, driftwood, and clumps of plants such as Cryptocoryne or Java fern give them shady spots to hide and defend. A soft sand bottom is perfect because Apistogramma like to sift and dig, and it protects their delicate bellies as they patrol the floor of the tank.
Diet and feeding
In the wild they hunt tiny creatures in the leaf litter, so they prefer meaty foods. Feed them small live or frozen treats like baby brine shrimp, daphnia, and bloodworms, along with a good sinking pellet or flake. Feeding small amounts a couple of times a day keeps them colorful and active, and they especially love hunting live foods that wiggle.
Tankmates and temperament
Most of the time Apistogramma are peaceful and can share a tank with calm fish like small tetras and rasboras. Things change when they have babies, though. Parents become brave little guards and will chase away anything that comes near their fry, even fish much larger than themselves. Give them space and hiding spots so no one gets bullied.
Breeding and babies
Apistogramma are wonderful parents. The female usually lays her eggs on the roof of a cave, then fans them with her fins to keep them clean and full of oxygen. Once the babies hatch, she leads the tiny cloud of fry around the tank to feed while the father patrols the borders. Watching a mother herd her babies is one of the best sights in the hobby.
Fun facts
- There are more than 90 known species of Apistogramma, and scientists keep discovering new ones.
- Male Apistogramma are much more colorful than females, who are often plain yellow.
- They live in the same tea-colored, leaf-filled streams as many wild bettas and tetras.
- A mother dwarf cichlid can change color to a bright warning yellow when defending her fry.
- Their name comes from Greek words that roughly mean 'unreliable line', because of the broken pattern along their sides.
Frequently asked questions
Are Apistogramma good for beginners?
They are a step up from starter fish because they like soft, clean, slightly acidic water. A keeper who has kept a tank for a while and can do regular water changes will do great with them.
Can I keep two males together?
In a small tank two males will usually fight over territory. It is safer to keep one male with one or more females, or give them a large, heavily decorated tank with lots of sight breaks.
What water do they need?
Warm water around 78°F, soft and slightly acidic, works best. Adding dried leaves or driftwood helps recreate their natural stream water.
Do they really take care of their babies?
Yes. Apistogramma are famous for being caring parents. The female guards and guides the fry while the male protects the territory, which is rare and fun to watch.
