Well Pin-pin I've kept quite alot of species and these do have a quite amaible look, almost look like they are toy-like. Hey even my wife liked them and in fact she was upset when I gave away my first group (so this is my 2nd group). Aside my Hynobidae & Ambystomatidae (my 2 preferate genera) I keep some other species too ... for instance I still hang on to a group of 26 axolotls & about 14 cynops pyrrhogaster a solitary cynops ensicauda, .... but I keep quite less animals now then before. In the past I had about 160 tanks to take care of. I couldn't do this anymore, now I'm down to about 40
