No. However, it can cause allergies on some folks and high protein may cause some fish to bloat or float.

Almost every coworker who had been there for a while at my old job at a wholesaler was allergic to bloodworms. They insisted it was from repeat exposure over the years.

The oscar could be sensitive to high protein. That's kinda the opposite of what they are supposed to be. Anything low in protein will be better for him.
