How do I care for baby convict cichlids in a home tank?

Published October 29, 2026

The short answer

Baby convict cichlids are the easiest cichlid fry to raise and the hardest to rehome: both parents guard the free-swimming brood fiercely, the fry take powdered food and baby brine shrimp readily, and your real jobs are protecting tankmates from the parents and planning homes for very large numbers of youngsters. Keep the family in their own tank if possible and separate growing juveniles before the parents spawn again. KinsLe's Care Teams helps you track the separations, feedings, and tank moves a convict family generates.

Baby convict cichlids invert the usual fry problem. With most fish, you struggle to keep babies alive; with convicts, fiercely guarded by both parents and willing to eat almost anything small, you struggle to keep up with how many survive. A pair will clean a cave or flowerpot, lay eggs, and emerge days later escorting a pulsing cloud of fry around the tank like two striped security guards. Home care is less about delicate feeding and more about management: protecting other fish from the parents, feeding the cloud simply, separating youngsters in time, and having an honest plan for the sheer number of convict cichlids one loving pair can produce.

Give the family a tank of their own

A guarding convict pair will claim half of a community tank and defend it against fish many times their size, so the kindest setup for everyone is a dedicated tank for the family. Inside it, your work is minimal at first: the parents fan the eggs, move the wrigglers to pits they dig, and then lead the free-swimming brood to food, calling them back with body signals when your hand approaches. Watch that both parents stay attentive and that the brood stays in one cloud rather than scattering, which usually signals disturbance. Beyond keeping the water clean and the filter intake covered or sponged so fry are not drawn in, the parents genuinely need little help.

Feed the cloud simply and often

Free-swimming convict fry accept finely powdered fry food, crushed flake, and baby brine shrimp from the start, delivered gently toward the brood with a pipette or a pinch released near them. The parents will guide the cloud over food you provide and also lead them to graze algae and micro-organisms from surfaces, so a mature tank with some algae growth raises hardier fry than a sterile one. Feed small amounts several times a day and siphon the family's territory carefully, since the parents will treat a siphon tube as an invader and attack it, which is alarming but normal. Work slowly, let them posture, and the cleaning gets done with minimal stress on all three generations involved.

Separate youngsters before the next spawning

The family's peace has an expiry date. Within weeks the parents typically want to spawn again, and the current fry transform in their eyes from treasure to trespassers. Move juveniles to a grow-out tank before that turn, because a pair driving off a hundred youngsters in a confined tank causes real injuries. In the grow-out, the youngsters' own hierarchy starts immediately, so provide broken sight lines, multiple shelters, and more space than looks necessary. Grade by size if growth diverges, since the smallest juveniles are bullied at feeding time, and a second feeding point at the tank's far end restores fairness cheaply.

Face the rehoming question early and honestly

A single convict brood can produce well over a hundred juveniles, and convicts are so commonly bred that shops and other keepers are rarely short of them. Decide before the fry are free-swimming where they will go: a shop that agreed in advance, local keepers, or a hard personal limit on how many you raise. Letting a pair raise every brood to size with no destination is how one tank becomes five. Some keepers keep a beloved pair and raise a brood occasionally as the fascinating family spectacle it is. That is a perfectly good reason to breed convicts, provided the youngsters' future was arranged while they were still a cloud at their parents' fins.

Keep the family's many moves organised

Separations, grow-out moves, feedings for two tanks, and rehoming arrangements give a convict family an administrative life beyond the aquarium glass. It is easy to lose track of which tank holds which batch and when the juveniles must move by. Recording the family's feedings, moves, and headcounts in KinsLe's Care Teams lets everyone helping know the current state of each batch, with completed tasks marked by a timestamp, so the parents' next spawning never catches the household with the previous brood still unhoused and nowhere planned for them to go.
