A sad clown

[starfish9]

I'm getting a bit concerned about my dominant clownfish. She's been really quiet lately, not eating as much as usual, and now she's gasping for air and not swimming around like she used to. Her mouth is constantly moving, way more than the other fish, but at least she's sticking near the bottom. The tank's parameters all look fine to me, no major changes except for that new skimmer which is working a lot better than the old one. I even added an airstone for a bit to see if it was an oxygen thing, but no difference. Any ideas what's going on?

Gasping can be a sign of gill flukes or even an ammonia or nitrite spike, though you've mentioned the tank parameters seem fine. How's the rest of the tank's inhabitants doing, any other fish showing similar symptoms?

The rest of the tank's inhabitants seem to be doing alright, the other clownfish is active and the gobies are their usual selves. The other clown's been trying to get her to play, but she's just not interested. I'll look into gill flukes and run some more tests, though the parameters have been steady so far.

Heartbroken, lost my little clown. Really appreciate the advice, though - I'll be keeping a close eye on the others now, especially after what happened to her.
