The last time I tried was last Monday, so tonight I'm going to try again. He hasn't eaten in at least three weeks. (I've had him for two, and he hasn't eaten for me yet.) I have had all four sides of his tank blacked out and have avoided even looking at him through the top. Ugh, I really hope he takes it...! I want to get it right, so I'm debating between fully lively or stunned. I know he ate live when before I got him, but when I put a live one in his tank last time, he balled up in a corner and looked terrified of it. He at least sniffed at the stunned one before snubbing it. I just don't want to traumatize him and put him off feeding for another three weeks...
