Okay, now I want a community tank. I would really like a mystery snail, a crawfish, and a couple of fish. (i was reading that as long as the fish are larger than the crawfish it shouldn't bother them). IDK about the crawfish and the snail, though. I saw on a forum that someone else did keep them together. Any suggestions on fish? I would like about 3 fish (besides the crawfish and/or snail). What size tank? Which fish do you add first and how long in between adding new ones? How long do you have to let the tank run before adding anything? I am prepared for this to be a very long process. I just need a hobby, lol. I am heading to the flea market to look for cheap aquariums now. (not prepared to purchase today, just seeing what's available, maybe put something on layaway.) Also may check out a bookstore to see if I can find a guide or dummy book on freshwater community tanks.
