Diet: HerbivoreThough Silver Dollars are widely believed to be herbivores, they are omnivores and will eat a variety of foods with a somewhat voracious appetite. Flake food, bloodworms, daphnia and brine shrimp are all excellent options as well as peas, potatoes and fresh fruit. The key to keeping a school of Silver Dollars in peak condition is to vary their diet often. Be warned! If you have aquatic plants these little fish will nibble them down to nothing.Even though the Silver Dollar prefers a vegetarian diet, they will eat meaty foods as treats. They are especially fond of bloodworms, mosquito larvae (glass worms), and brine shrimp. If the Silver Dollar is in a community tank, watch them at feeding time to ensure that more active and aggressive fish don’t get all the food. Silver Dollars can be rather timid in a crowd, and can end up underfed as a result.Even though the Silver Dollar prefers a vegetarian diet, they will eat meaty foods as treats.
