I figured it was something like that. Places like walmart that usually only have one "wall" of tanks are all connected to the same filter, I believe. I needed pond snails once when I used to keep puffers and they opened up the filtration system on the bottom to get the snails out (I guess they end up in the system, but they gave them to me for free) and it looked like all one unit, but then again, I didn't inspect the thing. Thanks Wendi.

Not a problem, I just happened to have ask the fish person at petco that same question. Or I wouldn't have known about it either.
