Hello, I'm new to keeping Ray's and I am having trouble getting mine to eat. I have only had him for 4 days so far, but the place I got him from told me he was eating 2 ghost shrimp a day before they shipped him to me. I have a 125 gal tank and a few other fish that I have had for a little while. I usually feed them frozen shrimp, beefheart, and worms. They are very quick when it comes to feeding time and it seems like the Ray gets more active, but doesn't seem to get anything. I have put several ghost shrimp in the tank at the same time and also tried to cut up some nightcrawlers. the other fish are just to fast and aggressive. I have seen him try to get a ghost shrimp, but not eat them even when they are almost walking on top on him and he seems to have no interest in the nightcrawlers. Temp is 79-80, amm 0, Nitrite 0 Thank You
