I currently have 3 red danios 2 blue rams 1 betta what else can i add?
It would be nice to provide the size of your tank to us? For informational purposes lets assume you have a 55 gallon (48*13*21), because anything significantly smaller than that will probably be over crowding your fish. So with a 55g, you can try a school of tetra's, neon, or cardinal, I recommend around 10. Also, I think red danios are schooling fish, so bump that number up to 6. Then get some fish that stay at the bottom, for a 55 gallon, I recommend 1 (bristle nose plecostomus), 8(panda corydoras), and maybe a snail or 2, and you should be pretty full.
The tank is a 75 gal according to the thread header. The betta is what will make your tank hard to stock, not the GBRs. The suggestions in the post above where good, I can't think of much else at the moment that wouldn't cause problems potentually with the betta... well platies might work....
would some angels and 7 neons be ok? cameron i cant find any corydoras at any lfs
