70 gallon alage eaters?

[OpenOcean33]

So, I am looking for a good alage eater for my 70 gallon. I have plenty of snail and hermits but looking for my herbivore fish. I saw the lawnmower blenny and tailspin blenny as options. What else do you suggest ? Or out of the two which would be best ? Tank is currently stocked with 2 clowns a wrasse and flame angel.

Had a lawnmower blenny for a decent while in my 32 and later a 55. In both tanks I am confident he was the main contributor to algae cleanup, had his lips on the glass/rocks 24/7. Also was a model citizen.
