I seriously hate that I only come to this website for help, and it always seems like the same stuff...
For the past few days the ends of Finnick's caudal fin have been clear. I assumed this was growth; he had gone through what I assume was a tail nipping episode, and it was just the fin growing back between the frays. I come back only a few hours later from last seeing him and now all that transparent fin is gone and maybe even a little of his "healthy" fin.
I don't get it. I thought the clear part growing between the frays from his last episode was supposed to be regrowth, but now it's gone. It happens when I'm not around. Is it nipping? Or is the transparency actually a sign of fin rot?
