It would be nice to be able to keep these guys in tubs, but I doubt I could keep the water cool enough during the summers.

Put them in large tubs (100+ gallons), bury partially in the ground to balance temperature, and keep in the shade. Add airline with air-stone and / or external pump that dumps water back in to keep water moving. Warm water is OK as long as there is enough dissolved oxygen.

Just a rambling video. Tank us looking a bit worse for the wear… lots of algae. But fish are thriving. Got sone aggression going on between two Banded Sunfish. R. Shiners are still spawning now and then. Small cache of fry doing well in floating flow-through container.

I’m quite excited to be starting a Rainbow Shiner aquarium setup at home. I’ve sold off the Emerald Killifish, and plan to do a long term Rainbow Shiner breeding setup here in the 33-long. The Rainbows may have a “bluer” cast to them. I’ll keep this thread active…

I’m now working with two lines of Rainbow shiners. My first line fired up today, and dropped some eggs..,



(Added stone catcher… then several hours later…)


Now, yesterday, I got a very small batch of Rainbow Shiners with a more blue caste…





Now, SOME of that color is from LED lighting. But on the whole, there is a difference.

No eggs yet from newbies.

Notropis chrosomus colony tank, showing three distinct stages of growth…


Am I the only one that can’t see any pics?  I’m finally catching up after a very busy weekend, but I don’t see 3 stages of anything here.  🤷🏻‍♀️
