Stan Sung took this photo of rainbow shiners breeding en masse in Collinsville, Alabama, two weeks ago. The male fish are easy to see, they're the clumps of brilliant red with hints of electric blue. The water is about mid-calf deep, and obviously very clear. Stan and his group were lucky, they were in the right place at the right time.

No, we have no water temp. from that shot. Estill Fork in the upper Paint Rock system was 13 deg. C at about the same time, so I'd guess that in Collinsville it would be the same or slightly warmer.

Yeah

This may have already been posted, but here's a video by William Roston of some spawning mode Rainbows in a stream.

From the video the fish seems less red/purple with more blue patches. Pics of orgy spawning fish [fireball] seems to match Mr. Stan's pic better. Maybe it's just less light in the video?

I don't know the details of the video, or what state they were in at the time of being shot. Maybe they weren't spawning? I'm not sure. It does look like the picture was taken in perhaps a more sunlit area though. Does anyone know much about variation in Rainbows? Maybe Roston just had a more blue/purple population?

Yes, rainbows seem to vary along a SW/NE gradient within their range. Collinsville is pretty much at the NE pole, and they're markedly redder than the ones from, say, Centerville to the SW of Birmingham. I'm not familiar with rainbows from further to the south.

Does anyone know what area were Mr. Roston's video taken though?

The bright red/purple color is the fire-up orgy color that is not everyday color. You can search the forum for pics of both fire-up and normal color.

I think Roston did his work with a southern population of rainbow shiners.

Ive taken rainbow shiner pix and every shot comes out looking like a different fish due to lighting and camera issues, as well as the fish's own capacity for very rapid chromatophore contraction and expansion.

Chrosomus in aquaria can color up and breed all year round, without any winter chill or nest-building host. (Mine stay 70 to 80 F year round).
Its one of the all-around easiest shiners to keep and breed, lives 5+ yrs, and males aren't terribly quarrelsome as long as they're in a school of 8 more.

If youre looking for some, Eric Bodrock at All Oddball Aquatics in NJ breeds and sells them. His stock is from the Centreville AL population.

When in full orgy/fireball mode in my tanks the blue patches on the rainbows seem to constrict a little bit and slightly less obvious than in normal or slightly red [with red throat] mode. They can at least spawn in slightly red mode but doesn't form big orgy/fireball unlike when they turn totally red/purple with constricted blue.
