I named him casper the friendly jar and hopefully he stays that way haha but i wish the OP luck with his jar comm and hopefully he can find the jar he needs
I agree, mine is 18" the largest fish in the tank and the first one in the tank. It doesn't bother anybody. I've had that "other" jar before, one day all is good and the next day all is dead.
Good luck finding a friendly one.
