I’ve had this spotted mandarin for months now. This past week I’ve noticed it’s fins (the perching fins) and the lower portion of its tail are almost gone. Only other inhabitants are snails crabs a brittle star and a melanurus wrasse. I’ve watched the wrasse both closely and from afar and it’s honestly paid zero attention to my mandarin. It’s swimming just fine and eating like a pig and really acts like nothing is wrong. Noticed the fin issue one day like it popped up overnight. Only spot that seems like it may be getting worse is the tail. Thanks in advanced for any insight and help!
