I have a 14 BioCube also and right now, I just have a fire shrimp, margarita snail and hermit crab with ls and lr.
Wednesday, I will be getting a small pair of true percs and was hoping to be able to get them with the bubble anemone that they are already hosting at the LFS, but was told that the stock lighting in my BioCube was not enough to have this, and that they also require very well established tanks.
So, I am hoping that adding some frogspawn in there, maybe they will host that??
If you want a pair of clowns, I would recommend the percs because I don't think that they get as big as the maroons.
Good luck!
