Apistogramma Care Guide: Tank Size, Tankmates & Breeding
The apistogramma (genus Apistogramma) is one of the most rewarding fish in the freshwater hobby: a small, jewel-bright South American dwarf cichlid packed with color and personality, without the size or aggression of larger cichlids. We stock several species and color forms, including the Apistogramma cacatuoides (Cockatoo), the classic Apistogramma agassizii, the Panduro (panduro), and the Inka 50 (baenschi). You can browse what's currently available in our dwarf cichlids collection. One honest note up front: apistos are a little more sensitive to water quality than a beginner livebearer, so they reward keepers who already have a stable, cycled tank.
Meet the Apistogramma
Native to the soft, slow-moving waters of the Amazon basin, apistogrammas are true dwarf cichlids. Most males top out around 3 inches, while females stay noticeably smaller, often under 2 inches. The males are the showpieces, with flowing finnage, bold patterning, and intense color that varies dramatically by species. Females are smaller and plainer most of the year, but turn a striking bright yellow and become surprisingly bold when guarding eggs or fry. There are well over a hundred described species, so there is an apisto to suit almost any soft-water tank.
Tank Size and Setup
A single pair is comfortable in a 20-gallon long, and a 29-gallon or larger is better if you want a community or to keep one male with several females. Like most dwarf cichlids, apistos are cave spawners, so the most important thing you can provide is a hiding spot the female can claim: a small ceramic cave, a coconut shell, or a flowerpot turned on its side. Use a soft sand substrate so they can sift and dig, and break up sightlines with driftwood, leaf litter, and live plants. A gentle filter keeps the water clean without creating a strong current, which apistos dislike.
Water Parameters and Heating
This is where apistos ask a little more of you than a beginner fish. They are warm-water fish that do best between 78–82°F, so a reliable aquarium heater is essential. They prefer soft, acidic water, ideally a pH between 6.0 and 7.0, though many tank-bred fish adapt to slightly harder water. What matters most is stability and cleanliness: always run the tank through a fully completed nitrogen cycle before adding fish, treat tap water with a quality water conditioner, and stay consistent with weekly water changes using your maintenance supplies. Adding leaf litter or botanicals can help lower pH naturally and bring out their best color.
Feeding Your Apistogramma
Apistos are carnivorous micro-predators that relish small, meaty foods. They do best on a varied diet of high-quality sinking micro-pellets supplemented with protein-rich treats like frozen bloodworms, daphnia, and baby brine shrimp several times a week. Live or frozen foods are especially important when conditioning a pair to spawn. Because they feed near the bottom, choose foods that sink rather than float, and feed small amounts once or twice a day to keep the water pristine.
Tankmates and Temperament
Outside of breeding, apistogrammas are peaceful and make excellent residents of a soft-water community tank. They pair beautifully with small mid- and upper-water schoolers like tetras and pencilfish, which fill the open water while the apistos work the bottom. Peaceful bottom-dwellers such as corydoras catfish also make good companions. The main caveat is breeding: a guarding female becomes fearless and will chase fish many times her size away from her fry. In a larger, well-decorated tank this is manageable. Be cautious mixing apistos with dwarf shrimp, as the shrimp and their babies may be eaten.
Breeding Apistogramma
Watching apistos raise a brood is one of the highlights of keeping them. Give a healthy pair soft, warm, clean water, plenty of caves, and rich food, and they will often spawn on their own. The female lays her eggs inside a cave and takes the lead in guarding them, turning bright yellow and herding the fry once they are free-swimming, while the male defends the wider territory. Newly free-swimming fry can be fed baby brine shrimp and powdered foods. Depending on the species, apistos can be either pair-bonding or harem breeders, so it pays to research the specific fish you keep before setting up a breeding tank.
Is the Apistogramma Right for You?
If you want the color, intelligence, and parental behavior of a cichlid in a fish small enough for a planted community tank, the apistogramma is hard to beat. They are best suited to keepers who already have a stable, cycled aquarium and can offer soft, clean, warm water.

Frequently Asked Questions
Are apistogrammas good for beginners? They are a great "first cichlid" for someone who already keeps a stable, cycled community tank, but they are a bit more demanding about clean, soft water than starter fish like guppies, so they suit advanced beginners best.
What size tank do apistogrammas need? A 20-gallon long is enough for a single pair, while a 29-gallon or larger is better for a community tank or for keeping one male with multiple females.
Do apistogrammas need a heater? Yes. They are warm-water fish that prefer 78–82°F, so a reliable heater is essential to keep them healthy, colorful, and active.
