I really don't know how else to describe it. I've noticed it before, but today as I was looking at Finnick's water I noticed a good bit of it. It's these almost transparent flakes of various sizes. They remind me of flakes if you were to pick skin off of your lips or cut off the flap of a cut.
Now, I recently had an issue yesterday where I thought where there was clear growth on the end of Finnick's caudal fin for about a week, but last night it was gone. I've been wondering if it fell off or was bit off.
Is this those parts of that fin? Or is something else entirely? Does this tell me if the missing fin growth is from fin rot or tail biting?
