Right now I have a 40 gallon tank im about to start up with some small catfish. This will be i guess my "growing" tank, to raise the catfish till they are big enough to be put into a 125-150 i will also be buying shortly. I wanted to get these catfish: asain red tail, silver tip shark, sun cat, pictus, upside-down cat, as these are commonly available at my lfs. They are all about the same size right now, would this be ok?
