I have a 25 gallon tank with a few neons and two angels, and would like to get some more fish. These are my first angels and was wondering if anyone has had success with or know if Rams and angels are a good mix? I have also heard that Tiger Barbs can be added, but caution is required, and someone told me they have done it(mixed barbs and angels) and all their fish were just fine. Is this a good idea?
