so i now have this 2 RES w/c my sister just gave me. both of them eats voraciously when i feed them (pre-killed fish) at their aquarium but the water in it wont last a week!! i tried to put them into another container. the 1st 1 eats just well but the other is not touching his food.. so i placed him into another container but he/she still wont eat so when i placed him back into the aquarium and fed him IN the aquarium he was munching it like theres gonna be a food shortage or something... please help me with these guys.. is he sick or something? any suggestions?
