I am going to be setting up a tank(40-60gal) in the next few months, and I 'm trying to do all the research I can. The question I have right now, is can I use an under gravel filter system while using sand as my substrate? I know a lot of you will tell me NOT to use an under gravel system, but I'm just trying different ideas. I may be doing a Cichlid tank and having some other fish that are compatible as well like some bottom fish. It will be a planted tank as well whichever way I decide to go with fish species. My other thought is to do a tank with herbivores ONLY. Please give me your ideas for the larger tank size and/or fish.
