This should be pretty easy. We have a tropical fish tank, and among a few other species we have an adult pair of these guys. The female is a live-bearer, and seems to be giving birth to two young at a time. However, I can't for the life of me remember what kind of fish they are.


The male is in the foreground, and the female in the background. Any ideas?

I believe it is a Red Wag Platy (Xiphophorus maculatus)

This looks like a Red Wag Platy (Xiphophorus maculatus). Apparently it is a common tropical aquarium fish. Wikipedia does not show a picture of this variant. However a google image search with this will return the images of fish that you have shown.
