That's perfectly normal and nothing for you to worry about at all.Hi guys, sorry of I'm getting annoying...
This morning I noticed what looks like Rivers vent hanging out and I'm a little worried. I've been trying all morning to get a pic of her (try for 20 mins, fail, leave for half hour, try again). The one I've uploaded is the best I can get, you can see in the pic how stressed she is by the camera following her around so I don't really want to harass her any more if I can help it.

It's hard to see in the pic but just in front of her anal fin is a bump thingy hanging down. There's no other fish in the tank with her, the water is clean (90% change done yesterday morning), she still eats well and swims normally and all the rest I'm just worried it may be something to be concerned about... Is it?
Thanks in advance guys.
If she was about to lay eggs it would be protruding a lot more than that.
The fish looks perfectly healthy.
