lawnmower blenny the way to go?

i have an outbreak of GHA im fighting and at the moment its winning. i saw a lawnmower blenny at petco that was beautiful and was wondering if he would do what he sounds like he should and eat the grass we call gha lol. i do want a mandorin goby at some point so interaction with that fish is a must. as of now i have a b&w clown and a yt damsel. my tank info is in my sig. what do you guys and girls think?

 

petco? do they do trade ins? i would try to trade in the damsel for the blenny. if not IMO you would be full if you got the blenny. but think of it like this. your tank goes through stages, newer tanks get phases of algae. it will probably wear itself out if you dont provide to many nutrients. there are many ways to do this. less feedings is the main way. a blenny just gets rid of it, doenst tell you how to prevent in the future...etc

hope i helped ;D

 

i cut my feedings down to once every 3 days and i cut my light down to 5 hours a day. ive also been doing 5 gal water changes once a week. the cyno issue i had is prettymuch gone but the gha is thriving. i didnt think that fish would put me even close to my limit but i guess i was mistaken lol

 

not that its at the limit but you'd be full for a mandarin. sorry if i was clear. ill pm you with some of my helpful tips that i used againts GHA
