Some fish will acquire a taste for different foods over time, so don't worry about the sponge content too much. Sponge is a part of their diet but w/o it, they will do fine on other types of foods. Offer chopped mussell, clam, plankton, things like Emerald Entree, Marine Cuisine, mysis shrimp. Soaking these in supplements like selcon or zoe is a good idea. If you can get it, try Mega Marine Angel Formula by Hikari. Lots of sponge. All the angels I've kept really like it.
