Sick honey gourami

[rebeccasnewtank]

I have a honey gourami that's been ill for days, definitely not eating and only swimming when bumped by other fish. They also are becoming paler and seem bloated, per attached sideways pic.
Is there anything I can do to help the poor little one?
Thank you!

If it has stopped eating and bloated up overnight, then euthanise it because it has an internal infection and there's no cure.
