I found this info on another site. This is exactly what my Jewels and Texas Cichlids do.
Spawning usually takes place in pits dug into the substrate or in a cave if one is provided. Eggs generally number between 100 and 500. After fertilization, the eggs will be guarded by the female while the male patrols and defends the pair's territory. This is not a good time to be putting your hands in the tank for any reason, as Convicts have no problems attempting to remove fingers if you make the mistake of getting too close. Unfortunately, too close often means just looking at the tank. Convicts are one of the few cichlids that don't need more that one or two attempts to get the hang of being parents. Most pairs will get it right on the first spawning and will be excellent parents to all their spawns. Once the eggs have hatched after 2 to 3 days, the parents will transfer them to other small pits dug in the substrate around the tank. Both parents will continue to be extremely protective, defending their offspring against anything else that happens to be in the tank and many things that are just passing by outside the tank. Convict fry tend to be a little adventuresome and will take to wandering around the tank at an early age. The parents will attempt to keep them close by for the first few weeks and don't' be surprised if you see either parent picking up the fry in their mouths and spitting them back into the pit. After 2 to 4 weeks, the parents will probably be ready to spawn again and at this point it can be a good idea to remove the previous spawn if you have them in a small tank. Sometimes the parents will try to remove a previous spawn to make room for the next batch, but this doesn't always happen and the best idea is simply to watch the tank and see what your pair does.
