Question: Possible fin rot?

[SloppySlug]

Hi ,

We have 2 Axolotls, roughly 5-6 months old, and one of their tails have started looking frayed (See attached photos). Is this fin rot or is it possible the other one has nipped his tail ?

Any help would be greatly appreciated !

Thanks

It is hard to tell. He probably just got his tail nipped, but to be sure it isn't fin rot you should keep checking back on him. If it is fin rot, it will grow and continue to spread farther up his tail then into his body. However, that is unlikely. But just to be sure I would advise to keep checking in him to make sure it hasn't spread.
