accessories,rainbow gravel and a heater? I asked my dad and he said maybe, I only have 5 bucks and Petco sells Neon Tetras around 99¢ each. I also have a 5 gallon tank, Could i also use that?
No, neons are very sensitive to water quality and require 20+ gallons. They also require 6+ fish in a school. A betta is the only fish that is ok in 5+ gallons.
