Had a scarlet (Gimli) and blue (Legolas) for a couple weeks. Brought home an emerald (Boba) got them situated fine and went to bed, woke up to three red legs attached to a chunk of red rib meat on the sand bed. Found Gimli tucked into his favorite daytime hole and noticed his shell was a little cleaner. Figured they fought over territory. Fast forward 5 days and get home tonight and Gimli is on the highest point in the tank. All legs functional! Kinda blew my mind. Didn’t know they grew back. May have to rename Boba Fett to Goblin-king.
