Questions for new 275 gal IBC setup

[crazycoops]

Thanks for the sounds info and advice -- My tank is up and running now...just need to wait for the water temp to rise a little more so I can start establishing with some goldfish...won't be long before I add Tilapia...I want the important part of this to go right.

What I'm gathering is that I need to find some good fry and find my own breeding stock from there to be a safe bet. I found a couple of sources, but no response to questions of sterility or hormones...no response to me usually means it's a no go

[badflash]

Super Males don't carry hormone residue. Don't mix these up with sex reversed fish. Even sex reversed fish are dosed with relatively low amounts of testosterone for their 1st 4 weeks. It isn't like testosterone given to a 1/4" fry is going to do anything to you when they get to be a 2# fish. Don't fall for that stuff.

You can make supermales with no hormones, and you can do it yourself, it just takes a lot of time and testing.
