While we're discussing your current situation, there's nothing that would stop me from stocking a few dozen fatheads even from a local bait shop (assuming you were sure that's what you were getting) now.

Maybe spend $50 bucks or so.

I wouldn't do any major fish investment until the water quality questions were sorted out.
