Right or Wrong?

Male guppies CAN be a little aggressive but usually not to that point....

i never had glow lights before but cardinals tore off my males tale.. it was quite the thing to find a fin at the bottom of my tank cleaning one day.

The females never had a problem but the males tail was exceptionally large and i suppose too tempting for the faster and more numourous cardinals.

Maybe its also because i have a large school of cardinals and only had 3 guppies in the tank.

Hehe, like a male guppy could even get near a glo-light tetra...I wouldn't worry about it.
