So this morning, I noticed my black ear shark catfish was twitching while swimming. He wasn't going crazy or anything; he was swimming very slowly, and every now and then he would make some jerky movements that were definitely not normal. His mouth would open whenever he twitched; it almost seemed like he was choking on something, but I'm not sure. He's still doing it, and today is the first time I've ever seen him do this. Do any of you know what's wrong? Any advice will be appreciated.
