I kept my jar by itself from 2" until it was about 8" then I put my FRT and 1 L190 & 1 L330 both at 6". Now the jar is close to 20" still with the FRT, L190 & L330 and a motoro (all around 12") 2 10" tinfoil barbs and 1 6" gold coast cichlid. I am truly surprised how non hostile the jar is as the cichlid is constantly harassing the tinfoil barbs. Its been this way around a year
