I have 2 guppies left in my tank... my betta was moved, and my clown loach died from what I think was that I didn't wait a month in the beginning... my guppies are perfectly fine now but I want fish that would be OK to live in a 10 gallon tank, with 2 guppies at the top. I'm going to wait a month then put these in... I perfer smaller tetras and other peaceful fish. I am going to petsmart to get them.
