I am setting up a 200 or 240 gallon tank with a festae pair and a lot of silver dollars. I am adding a lot of rocks, driftwood and plants(fake most likely) for hiding spots. My question is, has anyone had success keeping small cichlids with large predatory cichlids like festae? If so what kind and do you have any recommendations? I realize that there is a chance it might not work regardless and any smaller fish might become expensive snacks.
