Since it will usually take the babies 4-6 weeks to be large enough to be released, a separate rearing aquarium is a better option than a breeder trap. This could be a 5-20 gallon tank with a sponge filter and a bare bottom. Having no substrate makes it easier to see uneaten food and vacuum it out after feeding. I use plastic plants with plant weights to provide some cover for the fish.
Our first experience with an egg-laying fish is usually the Convict Cichlid, a.k.a. The "Breeding Cichlid." The first sign that egg laying is imminent will usually be a pile of gravel moved out from behind a rock, and other fish being chased by the breeding pair. The female has a bright red belly and is usually smaller than the male. The eggs are laid on a rock and will take 3-5 days to hatch. Then the babies will be wigglers for 1-2 more days. During this time, it is not unusual to see the parents using their mouths to move the fry to a more secure location. After the fry are free swimming, the parents will herd the babies for a few days until the effort is too much. At that point, the babies have to fend for themselves, and the parents are ready to spawn again.
Once again, if you want to raise the babies, it is best to remove the rock with the eggs attached to a hatch-out/rearing tank. Fill this tank with water from the display aquarium. Do not allow the rock and eggs to be exposed to air during the transfer; encircle it with a plastic container or bag before removing it from the aquarium. You can feed the babies freshly hatched brine shrimp, TetraMin baby food "E" or standard flakes which have been ground into a powder -msn.fish.com-
