Albino, green/patternless, granite, labyrinth, caramel/blonde, hypo/leucistic (also several combinations of the ones listed)... think there may be a couple others too. I think that's a fair number considering in most species you don't really see many mutations. Since they are a threatened species in their native land, the chances of finding any new mutations in the wild now are somewhat low. It's pretty rare for any to pop up randomly through captive breeding as well.
