Ill ocellaris?

[leezard]

Woke up this morning and turned the fish lights on, and our female ocellaris (AKA "Ted") was having... buoyancy issues? She kept floating to her side and I was sure we were coming home to a dead fishy after work today. She seems fine and dandy, now -- swimming normally, eating, playing in the water flows. I'm a little confused (and worried. I don't think I"ve ever worried about a fish before, truthfully).

I did a 10% water change yesterday, and the only thing that seems out of place is my nitrates, which is sitting at about 10 ppm -- not much lower than yesterday before the water change.

The only other thing I can think of is possibly the skimmer stressed her out? It's the Tunze Nano Skimmer (on a 20 g) -- and yes, I'm aware that it's had bad reviews. We've had it running, but silly me was playing with the wrong adjustment so it didn't actually start skimming until last night.

Any ideas? Could she actually be dying, or does she just need a dose of "caffeine" in the morning like I do?



(Yes, I'm kidding about the caffeine..... well, not my dosage..... you know.)
