Thanks!
I've been leaving him alone and he's pretty much just been basking and pacing around the tank the past week. He didn't eat any of the minnows last weekend so I waited until today to offer him a pinky. He struck at it and held on, even ripping it from the forceps. I held completely still so that I didn't freak him out or anything, but he just randomly spit it out and crawled away. I left it in there for a while but he wasn't interested.
Oh well- next week!
