I've received conflicting information about how big a jardini can grow. There's a 6 inch jardini at my lfs, and I am interested in puttin him in with my dats until i can get a bigger tank ( i have a 125 gal. ). My questions are how big do they get in captivity, will they get along with dats that are too big to fit in it's mouth, and is a 125 big enough for a single jardini?
