Why Apistos Are Special
Apistogramma species fit in 20-gallon tanks, breed reliably, and display all the personality of larger cichlids in a smaller package. Males develop dramatic finnage and color; females turn bright yellow when guarding fry.
60+ described species exist, with new ones discovered yearly. The genus offers something for every keeper — from beginner-friendly cacatuoides to advanced wild-only types.
Tank Setup
Minimum 20-gallon long for a pair. 40-gallon long for a colony of 1 male + 3 females + dither fish.
Plant heavily. Provide cave structures (ceramic spawning caves, coconut shells, half-flowerpots). Each female needs her own cave for territorial breeding.
Sand substrate. Driftwood. Indian almond leaves on the bottom for natural blackwater conditioning.
Water Parameters
Temperature: 78–84°F (26–29°C).
pH: 5.5–7.0 (lower for wild specimens).
GH: 1–6 (very soft).
KH: 0–4.
Nitrates: under 15 ppm.
Most tap water needs RO mixing for breeding success.
Recommended Species
Apistogramma cacatuoides (Cockatoo Cichlid): hardy, beginner-friendly, available in orange, red, and triple-red varieties. Tolerates pH 6.5–7.5.
Apistogramma agassizii: classic Amazon species, requires softer water. Multiple color forms (red, blue, gold).
Apistogramma borellii: peaceful, smaller, tolerates cooler temperatures (74°F+). Yellow-blue.
Apistogramma macmasteri: red-tail variety, requires very soft water.
Apistogramma trifasciata: stripe-pattern, somewhat aggressive.
Breeding
Apistos are cave-spawners. Female lays 50–150 eggs on the cave ceiling, fans them, and chases off everything else (including the male).
Male defends the larger territory while female cares for fry. Fry free-swimming at 7 days.
Feed fry: micro-worms, baby brine shrimp, then crushed flake. Female protects fry for 2–3 weeks.
Tank Mates
Best dither fish: small tetras (cardinal, ember, neon), pencil fish, hatchet fish, corydoras (sterbai or pygmy).
Avoid: barbs (too aggressive), large gouramis (territorial), other cichlids (compete for caves).
