Instructions
Place a substrate of fine sand in the bottom of the aquarium that will serve as your breeding tank. Cockatoo cichlids are most comfortable with this substrate as it mimics their natural environment.
Place several caves in the aquarium. Include at least one cave structure for each female fish. These caves can be created from rocks, coconut halves, fake aquarium decorations, or upturned flowerpots. The caves must be large enough that both the male and female fish can enter.
Adjust the water temperature in the aquarium to between 78 and 84 degrees. This is slightly warmer than what cockatoo cichlids usually prefer, and should induce breeding.
Monitor the pH and hardness levels of the water using a water testing kit. Although cockatoo cichlids usually tolerate high pH levels, a pH level of 6.8 and 7.2 is required for the eggs to hatch. The water hardness level should be 10 or lower. Both of these levels can be adjusted with water additives.
Introduce a group of cockatoo cichlids into the aquarium. This group can include one male and one female, or one male and several females. The number of fish you can breed depends upon the size of your aquarium, as each additional fish will require additional space. You can determine which fish are male and which are female by looking at the coloring. Male cockatoo cichlids are brighter in color, while the females are a dull yellow. Males are also much larger and have a crested dorsal fin.
Ensure the fish you have selected to breed all have straight spines. Because cockatoo cichlids are often interbred for specific colors, problems with the spines often develop. Never breed a fish that has a spinal problem.
Feed the cockatoo cichlids live foods, such as brine shrimp. This nutritious diet will encourage breeding.
Wait for the fish to breed. This should happen almost right away when the water conditions are correct and the fish are being fed live food. The female will entice the male into the cave she has claimed then lay the eggs in the cave. The male will enter the cave long enough to fertilize the eggs. The female fish will then guard the eggs, while the male guards the female. The eggs will hatch in three to four days, and the female will continue to guard the young fish after they hatch.
