I bought this eel marketed as a freshwater moray. I know they are brackish. My ? Is what is the best thing to feed it? I've tried clams on the half shell, fresh frozen uncooked shrimp, brine shrimp, gammarus, frozen silversides, and live feeder fish. It's been two weeks and I'm still not sure if it's eating because it's in a tank with a GSP that eats everything.
