Another good fish to breed is the Pink Convict. Like mollies they are very easy to breed and the babies are hardy and easy to raise. But Pink Convicts are an aggressive fish, and the details of their breeding are quite different from livebearers such as the Mollies discussed above. A male and female Pink Convict form a lasting pair and work together to chase the other fish out of their territory. They'll dig in the gravel to form a pit, or sometimes they'll dig a cave out from under a rock. In the pit or in the cave on the side of a rock they'll lay their eggs, and then carefully protect their eggs from other fish. After three or four days the eggs hatch into tiny fish fry.
The best way to get a pair of Pink Convicts is to get six or eight Pink Convicts about 1" to 1.5" long. Put them in an aquarium with at least 20 gallons of water and raise them up. Usually by the time they have grown to 2", one of the males and one of the females will pair off, work together to establish a territory, chase other fish out of that territory, lay eggs, and raise their babies.
2. If your Pink Convict Cichlids do not spawn, here are three things you can do to encourage them.(1) Change 20% of the water in their aquarium each day. Click here for more about changing water in aquariums.
(2) Increase the temperature of the water by 2 degrees F. So for example, if the temperature is 78, increase it to 80 degrees. This requires only a very slight turn of the dial on the aquarium heater. Do not increase the temperature above 82 degrees F. Click here for more information about adjusting aquarium heaters.
(3) Feed more good food to your adult Pink Convicts. Feed them floating flake food and freeze dried blood worms. If you can obtain live or frozen brine shrimp, feed a few of them each day to your Convicts. If you can get Live Black Worms, feed each of of your Convict Cichlids about 3 worms each day.
