a six line wrasse, yellow headed sleeper goby, cleaner wrasse (don't know how this thing is still alive!) a tru perc and a clown goby. i know they're not picking on the sally and my emeralds are too small to even consider challenging it.
the sally actually climbed our UV sterilizer and cleaned the sides of it and the back wall. cleaned all 6 of our snails, too!! i swear it can scale walls sometimes...
