1st is a lepidota, female with pink/red belly
2nd looks like a Johanna, maybe male, no red belly
3rd looks like a cincta except for that red stripe, only have seen black and white. But not everything has been documented so it might be. The lines arent thick enough for Stocki or punctata.
man, I dont even care, how much, Im going get a tank (or two), pool, empty the 150, something. they look badazz
