Thanks Puffer!
About the G. Bahia Red, no that isn't her home. She was just going under there to hide because they are all very camera shy! If I didn't have a lid on the tank they would jump out when I come around with the camera. I can be 6 feet away and if they see the camera, they won't stop watching me no matter what I do, even tried crawling on the floor to the tank but they still saw me! The large male uses that shelf as his home and he has done all kinds of redecorating in there. Except for when the camera comes out, none of the others can get near his territory.
