Good morning Aquarist..
I know just what you mean by the new toys for the BRs. I have to laugh every time I watch them peeking out of the caves. Remember the kids game "musical chairs"? Well... lol.. thats what my guys remind me of when they are trying to find a pot to hide in. Last one to find a cave looses. They are such characters.

Im going to have to make a video of these guys..
Mine are still skittish at vacuum time, but they just stay in the terra cotta pots while Im working on the tank. It takes awhile after a
water change/cleaning for them to feel comfortable with me around the tank.
