Thanks for the advise. This is a one year old male so he's pretty small. I usually see him out in his tank at night and it's been at least 2 nights since I've seen him out so he could be just about anywhere! We have a 2 story heavily furnished and cluttered house. AAUUGGHH. I'll let you know if he shows up. I'm also going to try putting out a fuzzy tonight in a low spot and see if he goes for it.
