We tried to find a Bristlenose Pleco recently but they didn't have any at one of the largest fish stores in Tokyo. If we cannot find one to be a hardworking algae eater for at least one of our tanks, what should we do? Should we look at buying one online if possible? Or can someone recommend some other types of algae-eating catfish? How about buying a solution to add to the water to decrease algae growth? I would prefer not to use chemicals but algae seems to be the main problem with our tanks. Any suggestions?
