I seen 2 of these fish at LFS today and want to buy them but did not because I don't have any experience with them, or even herd of them till today. Has anybody had any of these fish? How do they act? Would I be able to put 2 of them about 3 inch's in a 75 gallon with CA cichlids. I read on 1 sight that there aggressive and mean then another site will say they very peaceful, so not to sure about what to think of um. Any info will help, thanks!
