Mystery Solved! Didn't know I had a mystery haha. Talking about DAVE's mysterious behavior, Dave who is a sand sifting cucumber, Dave who apparently is not a sand sifter cuc but a filter feeding cuc!
He was on the glass last night again (and out and about) so I went to my pal google and learned there are 2 types of cucumbers: sand and filter. As I have NEVER seen Dave IN the sand or sifting sand but on rocks, and walls and along the edges of the tank, I conclude he is a filter feeder.
