I've never seen those fish/shrimp eat BBA, oto eat spot/dust/brown algaes, shrimp for certain types of hair, SAEs will eat hair and BBA and mosses and Rotala sp. and Mayaca sp. ...etc
Spot treat with peroxide, stay below 1/4cup / 50 gallons once a week and remove by hand if you don't want SAEs... You might be able to spot treat a little heavier than that, but I think what I recommended is pretty safe...
