HELP! Advice?

[marilyn]

Hi everyone.

There's something wrong with my lionfish, and I was wondering if anyone could tell me what's wrong with it. I noticed it yesterday, and it has this huge bump on his neck that shouldn't be there. What should I do? (or should I say NEED to do?)

Here's a picture of how my lionfish looks now.

Help! Any advice? Thanks.

Is he eating, listless, any other symptoms?

also, you don't have any fish missing do you? I'v seen this in a few large predatory freshwater fish that have tryed to swallw something too large which has just got stuck. from the pic it looks like something is stuck in there. seeing it has happened overnight, I can't see it being a tuma/growth etc. it may have swollen up, i.e. lump could be fluid of something? keep an eye on it and if he opens his mouth see if you can see if there is anything in there?
