Yeah no I wont literally raise him with them. I will grow him out till hes their size than introduce him. I have had pretty good success with my group so far with the eception of a silly choice. But I had to try and had to remove once or twice but I knew it wouldn't work long term so I tested my theory(Black Wolf fish).
I also have them on pellets and flakes although flakes are more for the Tinfoil and Black Orge Catfish. I feed insects and frozen`s like blood worms and krill, off shrimp and scallop or smelts. And of course occasional live Minnows I have a chance maybe to buy a Black for 100$ I think I might and grow it out than try in my 200 gallon and than worse case if it doesn't work, just good reason to get another big tank lol

But thanks for the tips and I love your setup man awesome !
