If you plan on harvesting fish from the pond, then RES will consume snails to help reduce fish parasite problems. RES often 'struggle' to maintain good densities when in with BG and LMB. A 'strong' RES population usually will essentially eliminate all the snails from a pond. If very large snails are present then that specie often can tolerate RES predation.

A few of the southern fish management places for growing good LMB suggest: ""Bluegill fingerlings should be stocked into new or renovated ponds at a rate of 1,000-2,000 per acre from October through March. Fall or early winter stockings are recommended to allow for maximum bluegill growth and reproduction before the bass are introduced in June. In established ponds that have become "bass-crowded", intermediate-sized bluegill are often introduced at the rate of 500-2,000 per acre to directly feed stunted bass and enhance the reproductive capacity of the bluegill population."

Since you added 1000BG into 0.5 ac you are at the higher stocking recommendation for panfish. Normally the RES will not eat pellets. If you see that snails are common in your pond and you plan to harvest panfish then you could stock some RES depending on how many snails are present for RES to eat. The existing 1000 BG are monopolizing the natural panfish foods. Adding some RES at 100-200 in 0.5ac could survive enough to provide snail control.
