I like the big fish as well, been keeping Oscars for a while, so nothing new to big goofy fish.. The LFS in town has an indoor pool (roughly 10', 3' deep in some places) and he has several big Oscars like mine, a few large brim, couple of cats, and plenty of huge Koi it it..Didnt even see the Oscars in it till it grabbed my finger while I was feeding the Koi..
I have been trying mine on mysis but he hits it and then spits it out,, of course I am still feeding live as well.. Gonna go a few days with the mysis only and see if he will come around..
I will give your threads a look..
Still havent decided if I want to do a 10' x 2'circle/square or just do a really long one, (14' x 4' x 2').. Building is 12' x 24' so I have room......Just have to get wifes outdoor one done first...
