Hey guys so im starting to see some algae growth in my tank and unfortunately i dont have any algae eaters in my tank!!! except for several snails. I was planning on picking up a lawnmower blenny but i had one before and he was pretty aggressive towards my other fishes. Im really leaning towards getting a yellow and blue tang but i only have a 75 gallon and i dont want any of my fishes to suffer due to space. Anyone have any suggestions? Which fish is a fatty when it comes of algae? BTW im not willing to spend an arm and a leg either. Thanks guys
