Sad clown(fish)

I don’t want to confuse correlation and causation, but I think it might have been low o2 saturation. Grasping at straws last night and I turned the skimmer on, it had been off for a week, and that’s about when the little guy went and hid in his normal spot. This morning he seems peppy, will see about getting a better picture if I can lure him out with food this morning.

Changes in aeration can cause major issues with fish. This can be from low oxygen, but also from high CO2. Skimmers do a great job at balancing gas exchange. Keep the skimmer going!

It is seriously embarrassing that I almost drowned my fish, and I will remember this lesson going forward.
