So I'm sure everyone knows the news about how bad tilapia is as a fish. Anywhere from its chemicals to nutrition to taste. I normally buy my food for my rays in bulk so about 6 months back I bought a few bags of tilapia fillets. I normally feed a mixture of shrimp and swai. But now that I'm running out of those I am starting to feel tilapia. It's been 5 days now. And my stingrays just swim over the tilapia. My fat female bites it every now and then but there is always a bunch left over. So I always just take it out. Today I soaked some shrimp heads with the tilapia and put a few pieces of shrimp. My rays found the shrimp out of the mixture with tilapia. My rays just hate tilapia...
