Today I bought 2 pictus catfish thinking that they may be one of the semi aggressive fish that can be placed in a community tank if they are provided with enough room. Well after researching them a bit, this isn't something I want to test with my fish seeing that odds are against me. Anyways, they are still in my 5G QT tank (they are only an inch each) and I figure I need to head out an buy a tank just for them and begin cycling it. So my question is what size tank should I get for these two fellows? They will be the only ones in the tank except maybe a snail or two.
