I was snaping shots of my tank, and when I looked down at my eel, he was coughing. Not really, but it looked like it. Or maybe he was trying to regurgitate something. I have no idea. Has this happened to anybody before? I want to know if there is anything I should be worried about. I was able to snap some shots of it because my camera was in hand. It only lasted about 10 seconds, until he was finally able to "cough." The section just after his gill outlets started to bulge (like as if he had something), and then he opened his mouth a couple of times until he finally smacked his head/neck against the sand, ultimately finishing off his little attack.
He looks fine right now, like nothing ever happened.
