I have two female guppies and one male born in the tank and now full grown. He's never bothered the females that much and they all spend most of the time apart.
Earlier I noticed the yellow female chasing him a bit, thought it was a bit odd but ignored it. Just been watching the tank for a few mins and saw both the yellow and other blue female chase and corner the male and then proceed to rip his tail off! A huge chunk was floating through the water, the poor thing. By the time I got a net to get him away from them, the whole tail has been ripped off, and when I found him he'd plastered himself to the underside of a leaf and looked pretty shocked. He's in a breeding net full of java moss now, just kind of sitting there.
Never seen anything like it before, seemed totally unprovoked. Weird.
