I am not sure how big my tank should be, I have 2 adult mollies that are about 3" long in a ten gallon tank with a feeder goldfish and a neon tetra if that's not right can someone tell me what I should be doing. The mollies were given to me as a gift and I have done some research and gotten so many different answers I am confused and annoyed. I love them because they are so friendly, they don't seem to mind the other fish. I also don't know what kind of rock sand gravel i should have in there or what kind of filtration. right now i am using what came in with the tank. yeah i know I am a newbie
