The school (6 individuals)has been in full swing, showing breeding behaviors for a few weeks. Obviously this male stands out. There are some Bonytail chubs (Gila elegans) and Razorback suckers (Xyrauchen texanus) in the background.

Just wanted to share the pic as this is a great looking individual for being a larger, native species.

Fantastic fish! I really enjoy seeing some of the North American species that we dont have in my part of the country.

Very cool looking fish. They have a very interesting spindle shaped profile. Are they Southwestern natives?

Yes. They have a very limited range in the Colorado River Basin. They have been extirpated from most of their historical range. Same as their tankmates.

Very nice. Are other Gila species turning red like this too? This reminds me of Tribolodon species in eastern Asia.

Nowhere near the extent that the Roundtails are. There is a distinctly gravid female Bonytail (G. elegans) and the males color up a little bit around the belly/pec fins. But it is very modest in comparison. I've not seen anything with the Razorback suckers yet.
