I think the 35 hex is fine for one angel but definetly not two of them. You can add a school of tetras that you like to go with him. I like the rummynose tetras. They are the tightest schoolers and are nice tankmates for an angelfish. I also like the diamond tetras. They are some of the larger tetras and will not be bothered by the angel if he decides to get pushy.
