No problem asking me.Britt told me you were asking a question.
I do not think the fish in your tank would bother the beta fish.None of the fish you have are aggressive.The only problem is beta fish in a community aquarium sometimes just hang around thebottom of the tank and do not seem too comfortable in a community aquarium.
You could try one, make sure it is a male and only get one,(two males will kill each other).
If it works out,and the beta does well,be careful with other fish you add to your tank because any kind of aggressive fish will try to nip at the long flowing fins of a beta fish. Good Luck!!
