Sweet blenny!! New addition to the tank?
Duh just reread first line...nevermind...cool fish promise and question...did you qt this fish? and do you at all...sorry for off topic..always been curious since I love your tank setup and livestock.
I do QT, since I work at an LFS I do it there. Blennies, gobies, and dragonets are reasonably safe ...but it's always good to QT anyway. Yes he's the new guy to replace Dr. Suess..my beloved little lawnmower.
