I feed mine a mixed diet of freeze dried hikari blood worms, whitefish, and occasionally beefheart. They also eat cichlid pellets. They can be a bit skittish and often territorial so I would deffinetly plan on doing more than one cave. Mine really love those terra cotta plant pots. I've tried replacing them with rocks several times but this is their hiding place of choice. When they breed they chase every other fish in the tank around all the time, they also make ditches in the sand all over the place. The females belly gets fat and the male gets reeeeeaaaallly bright. Then you will see eggs probably on a flat surface. Then the male fertilizes them and will fight to the death to protect them. There you go. Enjoy your fish
