best algae eater/cleaner

[Baho]

i have a 180 gallon tank wit some catfish and rainbowfish inside. I always have algae on the glass so im wondering which pleco is ideal to clean...

Bristle Nose Pleco's imo. But you cannot depend on a pleco to clean algae.
If you dont have any Large fish maybe Otocinclus Catfish they are supposed be good at cleaning algae but stay around 2".

Ever think of a flagtail?

What catfish do you have? Most catfish are predatory by nature. What species are your rainbowfish? Use algae scraper IMO. If you insist adding bioload, then try Ancistrus spp. or Panaque maccus however I do not agree using fish as a means to keep the algae at bay.
