Guys I rescued a fiery red oscar about 3" yesterday from my neighbor.. i have kept him alone in a 55g quarantine tank .. water parameters good and the filter is working well .. there is split in his caudal fin leaving it into two halves (which is not fully split till the root though) .. I have a aro and oscar community tank to which i will be transferring it after it catches some size .. all I want to know is will the fin unite to be one again ..
