My very young texas cichlids look like they are about to begin breeding. I do not have a clue in how to sex them, but the smaller one, about 2 inches has gone into breeding clors and is displaying for what I guess is the much larger females 4". Lots of digging going on too. So what age do this fish normally breed at? Are they good parents like convicts? How many eggs should I xpect with a successful breeding?
