i have a 9 inch dinosaur eel that has been in the tank for about a month. he eats plenty and is pretty mellow, but has always had little freak-outs on the occasion (including gulping for air).
He likes to hang out in this rock with a hole in it, and it seemed like he had residue on his body from doing so.
For a few weeks it sometimes caught my eye, almost like he had little soft flakes hanging from his scales. But I looked closely at him today and his whole right eye was covered in this clear-grey film that is made up of tiny, soft larvae-looking worms (just like a mosquito larvae) that are actually moving around on his face and fins and all the way down his body. They do summersaults- end over front- attaching the little end each time and inching along his body. He has been swimming around a lot more today, like he's trying to scrape them off and sticking his face in the bubbles and sitting there. It's very clear they are bothering him.
They are very small, i couldn't get a good enough picture. clear, maybe a millimeter or so, their ends seem brown. And they dangle from him when they aren't moving, they look like little cilia.
I've been looking and looking but everything I read about is either one thing or another, all of his symptoms don't fall under one thing. HELP! I freaked out when I realized they actually were parasites or something, so i did one ich treatment, i don't think it will hurt. if anyone can help, please do!
