Datnoid Fins fading?

[Rawrs.]

Is this possible fin rot? Water parameters are perfect and I have a BD ray in the tank.

Looks like fin rot. Maybe the dat is stressed out. Even in pics it has a dark look to it.

Yeah his buddy my arowana leaped out a few weeks ago and passed. So he’s stressed and hasn’t been stable in color since but he’s eating perfectly fine. Only him and my ray in the tank. Doesn’t look like fin rot to me but it’s definitely weird
