yeah,yeah, i know its a gamble blah blah blah. i just want to know if tankmates with your jar has worked for YOU, not your friends or what you have read. it just seems like i read ALOT of threads where people succesfully have tankmates with their jars, and others who havent tried or even own jars post that its not possible(me included, have a 5"er). just am curious on the success rate, as i am going to try to place my jar with my other fish when hes big enough.
