over the past year Ive raised guppies in my 10 and 30 gallon aquarriums. I have since found someone to buy what I have and plan to start a new. I was thinking about neon tetras because they were a childhood favorite of mine. I know they school and you need a min of 5-6 but how many could i put in the 30 and what would some good tank mates be for them. Also if you have a better idea of what to do let me know.
