A maintained freshwater tank and food is all that they really need. However, they are hearty feeders that must be well-fed or they may begin to nip at their long-finned tank-mates. Keeping the tetras in a school of 5 or more definitely decreases aggression. This species can occasionally nip at and eat aquarium plants. [4]
