i find the more you monkey with stuff the faster it all goes sideways, cons are great parents and before long your gonna curse those things they will take over your tank, your house and eventually the world , soon your city will become your dumping ground, ads on craigsslist for free con fry , and then you'll have to do the unthinkable and FEED something, i used to have a bullseye snakehead and he used to plow through 200 convict fry monthly, worked out well
try and get yourself some pink con fry and match em up with your guys, and through batch after batch of hand picking and raising fry make some calicos
and then sell some to me..
