I agree nice Salvinis......they can have the most stunning colors, and can also be the biggest bullies in almost any tank system. I had 3-4 inch female that nearly killed a few of my favorite fish so I gave it to my friend at my LFS......he tried putting her with all kinds of cichlids including Jags that were twice the size of her and she was beating the crap out of the jags.........He then wanted her gone so he put her with six 3-4 inch red belly piranas and she actually bullied the piranas around for like two weeks before they finally ate her one night....
