Sick pearl gourami!

[Cromid]

Hey guys, one of my pearl gouramis I’ve had for a couple years now seems to have become really unwell the past few weeks.
Losing colours, body shape, fins and tail is now completely drooping and doesn’t seem to have any control over it.
watched it and it’s still eating, although spending a lot more time gulping air at top of the tank. parameters seem to be within the tanks normal range of the past few years, so I have no clue as to why it’s suddenly looking so sick

Any ideas? Should I remove from the tank if it’s something contagious?

Do you have your actual parameters if possible? Have you introduced anything new to the tank recently? Tbh if it's contagious it's already in the tank so removing the fish may cause more stress.
