Jags are considered part of the castexi family and I do not doubt that they are but I wonder if they mature a lot faster then the other types. I posting some pics of my male jag and his lady. She is still right at 14 inch and he is 11 inch. When I put him in the pond a few months ago with her his claspers were maybe 3/4 of an inch long. They are now almost 2 inches and seem to get longer every day. I can't help but think that the female is mature already and the male is maturing faster because of it. Who knows what will happen in the future. The last pic is the female
She looks great!!!! Her tail looks like it belongs on a dinosaur.
