So sorry about the caps lock...just overlooked it. My fry are in a 10 G tank and the algea eater is about 2-3 inches big. My hubby says that it is safe since he IS an algea eater, but I'd like to be sure.
To be honest I wouldn't chance it. The algae eaters are very peaceful during the day but at night they can be very active and very fast. The can still eat fry - they don't stick to just algae. Mine loves bloodworm and other meaty treats.
