For my 120 gallon tank , a juvenile vlamingii tang is the only fish that totally cleared this bubble algae . Found this out by chance when a colleague bought this fish by mistake and he appeared at my doorstep with this fish in a bag . I wasnt too keen in having any tang in my tank but since I have a tank full of bubble algae , I told him just dump the fish in my tank . Less than a week , this fish single handedly cleared every bubble algae that I can see and then some .
But this fish grew ! It also was able to stand its own ground against my large green wrasse , which killed my mystery wrasse when I add it to the tank months before . Long story short , I traded both vlamingii and green wrasse for a group of firefish at my lfs . Not a single green bubble appeared again and this tank has been running since 2006 . Till now , there are no sighting of even a single bubble in my tank . Unfortunately , I am planning for a new tank as this current tank had a large scratch in the front pane of the glass .
