I keep a mixed flock of 7 neon and 4 glowlines. They are fun to watch cruising around the middle of my big tank. They've gotten big enough so that they come up and snatch pellets from my sorority girls at feeding time. The bettas are chill, they return the favor by eating some of the mini pellets for the tetras.
