Likely he's just a bit stressed Will from the jostling about as you moved his tank. Not that they can't or won't come out for a bit of a look around during the daylight hours, after all they aren't absolute on anything LOL, but I'd expect he's just a tad put out with being moved. It will likely pass quick enough as he settles back into the much quieter environment of your room.

Sounds like you are making some good steps forward with him and that's always wonderful to see.

Try not to disturb him overly with picture taking today and then leave him totally be for the next week so he can settle in and be better prepared for the feeding Saturday evening. Review good f/t feeding practices this week. There's a ton of threads here about that or just ask...we've a number of experienced f/t feeders as members here.

Don't lose heart with this situation. It's not always easy to get a BP eating if they haven't been well started but once they go, they tend to stay nicely to their routine. Pet store purchased babies are often the toughest ones so you've a bit of a challenge there but nothing that can't be dealt with step by step.
