I looked up some stuff cuz I had lost two discus before I learned that blood worms and beef heart have to much protein some how. But it caused a parasite in their intestine. The bellies swelled up and they died. All shortly after lack of eating now I'm using a pellet. Took some time for the to adjust but now they are very happy and always eat. I still do a brine shrimp treat every so often
This has been a great diet. They their share and the colors are amazing. It was really cheap online
