they get huge fast, great cat mine got to 16" the first yearpwmin;1652319; said:i don't think they are aggressive, they will just eat anything they can fit in their mouths...typical catfish and typical that they should eat quite a bit and not be too picky. I've never kept one, so take my advice with a grain of salt, lol. I have a couple LFS that have them and I am SO tempted to buy one every time, but they will get to 3' more quickly than I am prepared for at this time.
