A friend just inherited 2 of them while she was seizing other animals from a house. We aren't sure what they are. That is obviously not a picture of the ones she has, but they look exactly like them.
About the same size as a neon tetra - very long and thin, only bright orange with a whitish horizontal stripe.
I want to know what they are specifically so I can help her figure out how best to keep them. Right now she has them in a 1-2 gallon square tank, which I suspect is way too small for their swimming needs.
