I agree with all above, but if you decide to get an algae eater, you only options are: otos, great little algae eaters, stay small, around 2", but need groups of around 3-4 and are fairly sensitive to water quatlity. bristlenose plecos are fairly common and only get to around 4" in length, with some attaining a size sightly bigger than that. be sure to supplement their diet with fresh veggies and algae discs. also, some types of shrimp such as amano and cherry do good jobs eating some types of algae, but the only type i've ever seen them eat is hair. with i've heard peckoltias, a type of small pleco, do well too, but they are rare, and have a price corresponding to their avaliblity. also, be very aware that not all algae eaters will actualy eat algae, so cleaning it off yourself is a much better choice. also, i'd suggest testing you water to see if there is anything amiss with the water that could be causing the bloom. what does the algae look like?
