Hmm, I'm more concerned with the native fish.. I thought darters swam alot? These two hang around on the bottom and use their fins like legs.
I'm not sure about the orange fish(the guppy/endler thing is a feeder who slipped in the net), the male is about half an inch, and the female is around 1"... There were a few more of them, but they were torn up, so I didn't get them.
