What to know before you buy.
Often called 'Oto Cats,' these small catfish are exceptional algae eaters, perfect for planted tanks. They are peaceful and should be kept in groups to feel secure. They can be sensitive when first introduced to a tank and require a mature aquarium with a stable supply of biofilm and algae to thrive.
