I have 6 M. Praecox - Neon Dwarf Rainbows. Is a 15 gallon to small? I went through the computer and found many that say 20 gallon but two say 15 and one a 10 gallon. Thanks

I have 6 Neon Rainbowfish myself, and I must say they use up all of my 75 Gallon's open space for swimming. They are active fish and they get fairly large (3in) for a 15 gallon tank. I would suggest a 20 long at the smallest, but if you can go bigger I'd suggest a 30 long or a 55 standard. If you stick with the 15 gallon I'd suggest making sure you have a lot more filtration then the tank would normally get (like 200% tank filtration).
Mine used every inch of my 30g and I personally wont put them in anything less. There are some blue eye species small enough for that size tank though.
