It's been suggested a few times already but I'll add my opinion to the hat as well. A seahare will do you better on the filamentous algae than your rabbit or your lawnmower blenny. There are two main problems with seahares: 1) when the food source runs out they do tend to starve, more often than not. 2) They likely eventually will encounter a powerhead, pump intake or stream with sad results. And it's weird, because they can, for months, be fine walking all over pump intakes and walk off, but eventually they seem to run out of luck. But they are incredible algae eating machines that not much can compare to.
Rabbitfish are good at removing algaes but they tend to be particular to certain species.
Lawnmowers, as a rule, do not actually eat filamentous algae. Some may develop a taste for it but what they actually are eating when they do that lawnmower-gulp thing is going after slime algae. If you let slime accumulate on your glass you'll see the their kiss marks all over it.
How old is your tank? It's basically not uncommon for a new tank to go through a hair-pulling (sorry for the pun) phase of nuisance algaes. Hang in there!
