Angels are a type os cichlid and are notorious fin nippers. Those "see through fish" you mentioned may have been x-ray tetras and are also fin nippers, but being as they are not as aggressive as the Angels, the betta fought back. You might want to either put a divider in the tank to give him his own section or get him a small tank of his own anything over 2 gallons, or even a gallon is fine. But with the gallon you have to do either a 100% water change once a week or 50% water changes twice a week to keep the water quality good.
