| Shrimp will graze on the biofilm that covers just about every surface in an aquarium, but are particularly fond of dead/decaying vegetation. Sure, they'll eat flakes, pellets, whatever is available, but that's not their natural diet. IME they'll even help keep pleco poop from sitting around on the sand. I'm not sure whether they eat it, or just pick it apart to see if there's anything edible to be found, but my substrate has been noticeably cleaner since I dropped the cherry shrimp into the tank with the BN's and red lizards. |
