Anybody here have any of these? I recently caught about a dozen ice fishing, they were to small to clean so I brought them home and put them in my 70. Within a week they were eating Hikari gold from the surface like hogs. I've already moved 4 of them into my 220 cause they fattened up and grew so much in just a little over a month. I've had many natives before, but never perch. They are really cool, I love them!!! I was wondering if anyone else here has them and how big I can expect them to get in a 220gal tank. Thanks for your help.
