Frayed fins can be caused by ammonia. Ammonia burns the soft tissue in the fins as well as in the gills. Fungus or bacteria can move in on the injured areas, causing fin rot.
Keep the ammonia down with water changes until the nitrifying bacteria catch up. You can also read the label on your dechlorinator. Many will neutralize ammonia, but you might have to use a double dose.
That's what happened to my betta. His ammonia was high before I recognized the symptoms. He had been a sickly fish off and on since I rescued him, so I thought he was having another of his boughts. But, when he didn't start showing other symptoms, I decided to check his water. Poor guy, I didn't catch it in time.
With Frick and Frack it was only at the earliest stagesof Green in the Tube. Around .25, so minimal. It is a tank that is well established, so I think it was the removal of the carbon filter and change out of other filters that probably upset the ecosystem in there. Prime is something I have never used, but I did dose a bit higher than the suggested dose. I'm doing a partial water change every other day right now. Everyone is acting fine. No clamped fins. Normal behavior. So, hopefully there will be no issues and maybe I even caught it just as it was starting to go up (I had checked it a couple of days before and it was at 0 so it wasn't .25 for long).
