There are two kinds of "blue dolphin".. One is the hap. There's another one that is a Mbuna which uses that common name. I have some. It is a dark blue, with narrow black vertical stripes. I don't know the latin name.greenearthlawns;2855010; said:I thought they were mbuna some info I have found says they are sorry, i guess they are all terrors when they get big, too bad, at the moment though they are being cute and smimming around like dolfins, even ones that are supposed to be more peaceful can become brutal so I guess it all depends on tank mates, size temperment, etc...
