Platy top fin frayed?

[sea96]

Hey, I've noticed the top fin of one of my platies has changed in the past week or so.It looks frayed/splayed out, almost as if you've taken a few threads from a woven material if you get what I mean! I have attached a pic of anyone could help me understand the change, thanks

Try putting him in a quarantine tank and dose him with salt (aquarium salt is my go)

He may have fin rot. If not, then just keep on your water changes. It never hurts to be cautious.

It doesn't look like fin rot to me. For the shape itself is still intact. It's more that it seems that between each finray the fin tissue is breaking. This does happen from time to time in platies. But in general nothing to be worried about. As long as the shape of the dorsal is intact, there will be no treatment needed. If the dorsal gets ragged and it loses its shape, then fin rot is in play.
