I currently have some Harlequin Rasboras, some neon tetras, a betta, and an African Dwarf Frog. We just got a new ten gallon tank and are having difficulty deciding what to get. We liked a catfish that gets to be 5 inches, but opted against that. Then we were thinking an angel fish and one or two other small ones. Would this be too small for an angel? I read they need a tank that is 18 inches tall. Also, we had originally wanted a really neat looking exotic fish...but dont know what to get! And the ones we have seen are either very expensive (a blue tropheus for forty dollars a peice) or are aggressive and we aren't sure what to put in with it. So, does anyone have any ideas of a really beautiful fish suitable for this size tank? And some tankmates to go with it? Thanks in advance
