Ok, Michelangelo is starting to get a few on his shell, so I know you use a toothbrush to gently brush them off. Do you use anything else?
Also it looks like his shell is getting ready to shed, should I be extra careful so I don't pull off the scutes?
I'll probably be doing this in the next week or two as I plan on cleaning the tank during spring break. (since it takes so long) And I figured I'd clean him up when the water was clean too. That way everyone is clean for a while.
