When the African jewelfish is ready to breed, females will turn a deep red color to let the male know. The male and female will bond or jawlock and the male will release sperm on the eggs. The female will then lay the eggs on a flat surface. The female will protect her eggs and will kill anything that comes in close proximity. In a couple of days the eggs will hatch and the female will still protect them. The female can reproduce every three weeks.You’ll see a change in color, belly size, and aggression level. Cheers! If you still have problems address the primary concern of food, water parameters, and stress. Good Luck Mate!
