i tried it for weeks upon weeks. different tanks. more silvers. it just didn't work out for me. the jar was a rampage artist. big, small, long, thin, fat. no matter what i tried the jardini destroyed peace thats for sure. i seriously thought a 400gal tank would give him enough space to not be so bully like. but he was a menace...
good luck with yours, it never worked out for me. maybe for the first 2 weeks or so, but as soon as it felt comfortable it was all down hill from there.
