what type of aquarium tropical (heater needed) cold water or marine (saltwater)
They are tropical freshwater fish. They can be kept in an indoor heated tropical aquarium.
"Tropical" simply means the aquarium is kept above 60F. "Marine" simply means the water in the aquarium has had sea salt added to make the water into sea water. Therefore it is possible to have aquaria that are "Tropical", or "Marine", and also "Tropical marine".
