Yes I remember your post on little Reef when you rescued him. I'm glad to hear he is going well.
In regards to the tanks, I was going to suggest also keeping him out of the room while you are not there. Since this is not an option, the only thing I could think of , if it is at all possible, is putting them up somewhere high where Reef cannot get to them or take the tanks out of the room and keep Reef locked in the room since this place is his safe haven.
In the long run, I hope everything works out for you.

I would love to see an updated picture of Reef.
