I finally got my fish. 30 Bluegill and 10 channel cats. They have been in the tank for 24 hours now with no apparent issues. The catfish started eating immediately after release and the Bluegill were eating after a few minutes. Both groups were very busy swimming and didn't seem to have a preference of water depth.
Today the BG are still eating very well but the catfish have become reclusive. Did some water checks to make sure everything is in spec.
