Hi new member looking for advice. We have had a few black mollies in a new setup for around 2 months and the male seems to have had a change in his tail. It seems narrower, almost curved and is turning a silver colour.
This has been slowly changing over the last few weeks, water is fine and all other fish been healthy and no issues. Is this something we need to do something about? Attached a few photos to see if this will help.
Thanks in advance for any help
