Today i picked up three jags, the smallest is about 3" the biggest is about 5". The biggest is a male as it's vent was out and it was small and pointy. I'll try for some pictures later. They are sharing thee 149 gal tank with some Texas cichlids.
I Just had a look at them and noticed they were all in the top corner and were quite torn and my 6" green texas was giving them quite a chasing and beating, even though i moved everything around so i removed him and added him to a tank with my midas and he's calmed down.
