i hope i'm not wrong by saying tis... but i think as long as the jar can't fit the knife into his/her mouth it should be fine... but bewarned though... jar's haf a nasty habit of juz killing 4 the sake of killing... well tat's wad i've heard... cheers...
I have a BGK but i would not try it for a second with my jardini.
Beautiful fish not worth the risk my jar toasted 2 oscars and plenty of other fish just for fun... then again if you Have a massive tank and plenty of other fish in there it could work!
