I bought this guy from my LFS a few weeks ago and i cant get him to eat anything except frozen bloodworms. right now hes in a 30gallon with an 8 in striped raphael catfish.
he will get hungry and eventually eat anything that hits the top of the water, starve him for a couple of days then he will eat anything. it works every time. dont give in and get scared that your fish will die, he will be ok
