I recently acquired three juvenile Nicaragua Cichlids - about 2 inches long. After growing them out to 3 inches, I moved them into my 92 gallon bowfront. They are the smallest fish in the tank but large enough not to be lunch! Anyway, the female has developed stunning coloration - unlike many CA Cichilds, female nics are more colorful than the males. Along with the coloration, she has started to challenge one of the males, who stands his ground and then chases away the other male. Once I am convinced that they have paired, I will remove the remaining male or remove the pair to a breeding tank.
Does anyone know at what length they are sexually mature?
Here are some pictures of the two pairing nics. The female has a lot of turquoise on the face and dorsal fin; the male's stripe has started to fade and his dorsal fin is spotted.
