Well, at least he knows that... Hopefully he can find a suitable spot for them. There should be a BIG sign on the fish tanks for the tankbusters. In the fish store they are all about the same size. A newbie who does no research wouldn't know that some grow to massive proportions, and then there is that myth about a fish growing to the size of its tank, and the display tanks the fish are kept in are deceptive. They look really small, but the volume of water that's unseen is much larger.
