I'm going through the same thing for like 3 months now driving me crazy....i feed frozen krill, market shrimp, pellets, hikari foor sticks,shrimp pellets,myisiss shrimp, frozen silver sides, and all it eats is frozen red worms....lol my 2 8" NTTs,2 4" ATs, and my 5 8-9" indos have always been easy to turn and now eat all of it?
