I know I think I have written that I am buying a 75 gal in my signature... but for some reason, they are REALLY hard to find where I live. But I did see a 90gal, so I might buy that. Could a pair of Severums fit in a 90gal tank that is otherwise lightly stocked with schools of Serpae and Bleeding Heart Tetras, a Sailfin Pleco, and some Cories? Some people have a pair of Severums in their 75, but others recommend 100gal+ for a pair... thanks.
