hey guys. i have in my 55g tank a divider that divides the two sides. on the right side i have a 1.5 oscar with a pelco and a bala shark that is 2in. on the left side i have a mature 3in female jd and a immature 1 in jd. i was wondering if i could take the divider out. without them killin each other. but one problem i have is that the female jd when she was a baby she got sucked in the sump and has lived there without any oother fish untill about a month from when i bought her a the fish store and they told me she was verry aggresive. would it all work out?
