I've got two of Discus in a 55g that I've had for about six months. All I can get them to eat is Frozen Bloodworms. They spit out any other food types such as flakes, pellets, prepared frozen discus food ect. I've kinda tried slowly mixing in these food types with the blood worms but they just pick out the worms and leave the rest. Reminds me of being a kid and picking out the onions

One is a 7" wild brown and the other is a 4" leopard ss. What happens if I stop stressing about their diet and give in and just feed them blood worms? Will they get enough nutrients on a bw only diet ???
