Finishing up tank

[tillbarnem]

Hi everyone. First post on this site. I'm a little frustrated and need some help from some experts in westies. I have a 54 gallon tank, well planted, with rock ledges and plenty of chichlid caves. I have 2 Kribs that currently dominate in my tank. There are about 70 2 week old fry at this point in time. I have plenty of dither fish as well. I am looking for a different type of cichlid to put in the tank that satisfy the following requirements. They must not be too large, they must be able to stalemate with the Kribs, similar water parameters, and most likely either mouth brooder or flat rock brooder. Cichlids seem to love to breed in my tank. Any thoughts would be greatly appreciated. Thanks, Jeff
