I just glanced at my tank and my electric blue and gold jack dempsey is lying on the bottom of the tank kinked to his left side. I thought he was dead but when I looked at him he still moving his mouth and trying. I tried to move him with my net and he didn't (couldn't) wriggle. I've seen fish die they almost always wriggle. Nothing is moving but his mouth, I think he's paralyzed or in a state of.
What can I do?
