Identifying fin rot

[emf3198]

Hi folks,

I have a helfrichi firefish in 20G QT with cycled filter media. I noticed recently that there is a small split in his caudal fin. His other fins look to be in good shape. I tested for ammonia levels with a tropic Marin test kit and they don’t seem too high. I’d appreciate any opinions as to whether it looks like mechanical damage or if I should treat for fin rot. The fish has been eating well and is very active. (I know calcareous rock is not recommended in QT, but I haven’t decided if I will prophylactically medicate and I will dispose of it once the fish clears quarantine.) I appreciate your opinions!

This is a small fin split which will heal on its own as long as its not aggression from another fish. If medicating this tank, this rock will absorb medication and you will need to add more meds to get numbers up to treatment level or simply remove them

Thanks for weighing in! There are no other fish in the tank. I added the dry rock because the fish didn’t seem to like PVC fittings I put in the tank and I wanted to give it a place to hide, but I will remove if I decide to medicate to avoid absorption.

Thanks. Since you are on this topic. Would you say this is also rot or an infection?
