yeah, I like the a deccorated tank too.
But the problem seems to be that you hardly see some fish because most of them are nightly active. And that in all the cracks and holes, the dirt stacks up, so you have a constant source of pollution. Also you can't catch fish if you want them removed, or any way not nearly as easy as in a bare tank.
Im figuring out how to combine a deccorated tank with fish the best way. So that there's no place for dirt to pile up, I can see the fish (or any way most of the time) and I can fish out a fish when I want to with relative ease.
Maybe anyone @ MFK has some ideas or experiences??
