My creek chubs. Should be happy in 40ppm nitrate farm field run off.
I am planning on a cold water native tank. This spring I will get some fingerling from a local hatchery
Bass, crappie, walleye, a flat head. Feed then creek chubs. Then convince my loving wife that they need a 1000 gallons of space.
Probably build it zoo style cement, with one plane of 1" glass.
Then use my 30 gallon as a sump.
