I have a cycled 10 gallon tank that I would like to introduce a pair or single dwarf cichlid into. So far the tank has 3 pristella tetras, but if necesarry, they could be moved to another tank. I also plan on doing a moderate amount of planting in the tank. Does anyone have any suggestions for a somewhat readily available dwarf cichlid that would do well in this small of a tank? Also, should I go with a pair or a single fish. Finally, I was thinking of getting blue rams. Would they be happy in this tank? Thanks for any ideas or advice that you can give.
