My large female
percula clownfish started behaving strangely about 5 days ago. She has been lethargic just hanging out around the bottom of the tank, and sometimes even laying directly on the substrate. She hasn't been eating much. I noticed yesterday she was starting to lean to one side when swimming around.
Tonight I got home and found the clownfish hovering completely on her side about an inch above the floor not moving around at all. She is just flapping her fins, occasionaly freaking out like she is having a seizure. Her breathing is pretty rapid. Her coloring looks totally normal.
My tank is a small 30g with 2 clownfish, a baby niger trigger, 2 hermit crabs, and a
chocolate chip starfish. I tested the water and everything came up normal. My other two other fish look totally healthy, although I think my little clown is pretty upset about the other being sick.
Any ideas on what could be causing this? I'd be grateful for any possible solutions. I'd hate to loose her!
