These fish get up to about 5 inches. They like to be in schools of more females than males (if kept with more males than females they can be aggressive). Absolutely beautiful fish, they flash their colors from blue to green to yellow within seconds when excited.

I have 5 in my tank, but they aren't as 'swimmy' as most descriptions say that I've read. Mine hide in the corner, with only one swimming around. Any ideas?

Mine constantly move. Heavily planted tank with very peaceful tank mates. I keep my temp around 78 and pH is 7.4 (during the day) Water movement is above average. I have always slightly underfed my fish too though.
