Once in a while I saw my Totto fanning and he do dat when the lights out or nobody watching the tank. I sneaked him with torchlight.. haha.. after the 'black thingy' goes back in.. Totto will goes straight to the glass and show some angry face to me and open his mouth like want to bite me~ (maybe he try to say don't do that~! to him or maybe he just shy) ..
