Funny thing you guys, last night after reading your helpful advice, I went downstairs to watch him and just before I left I decided to throw in a FD krill and later come get if he didn't eat it. When I went back, NO KRILL ANYWHERE

. I threw in another one and left the room for 5 min and again it was gone

. I checked the entire tank (it's pretty much empty so it was easy) and there is nothing.
Guess he must've known that I was consulting with the experts, so he gave in. LOL.
YYYEEESSS, no more feeder goldfishes to buy every weekend.
