i have a 14" silver with a 12" jar they do this too but i does sometimes lead to the jar biting the silvers fins which leaves them a bit tatty. but usually they just swim around together.
mine did the same thing. it was the jar testing the silver. eventually the jar became stronger and overturned the silver. i had them togeother for about 2 years b4 i had to seperate them because the silver almost died. u might have better luck w the big tank.
Thanks....Not sure what to make of it-But I guess the end outcome is nothing is going to come of it...But maybe an ass beating...But who knows--Time will tell I guess
