I live in an apartment and have limited space. Right now I have a 10 gallon planted. After months of persistence, I think I have talked my wife into getting another tank. She is not into the hobby like I am, but she really likes the African dwarf frogs that I just got. Like I said it took awhile, but we have decided to get a 5 gallon for the bedroom. It may not be the 75 gallon I want but small steps. My stocking ideas for the tank are: 1 male betta, 2 African dwarf frogs, and maybe some shrimp. I have a medium sized fern in my 10 gallon that I think would be perfect for the new 5. My space is limited but I would also like a bottom feeder. I don't have any experience with snails and heard about how they can take over a tank. Also having problems deciding on a substrate, I like the black sand look, but will that work in a 5 gallon? Appreciate comments, suggestions or concerns with this setup.
