Today I needed some airline tubing so I could add another bottle to my DIY CO2, so for some reason I decided to go to the LFS I don't normally go to because its kinda hard to get to from my place. So I get there and they are having a sale on all fish where you buy 1 and get another of the same value for a penny. So I got 2 gold rams for $6.99! Just 1 problem though, all they had was males. So that's where my question lies. Is it at all possible to keep 2 male rams together in a 20 gallon tank? If not I guess I could take 1 back, I would lose my deal though.
