I woke this morning to find something wrong with my yellow tang. It is eating fine and looks great but it's anal fin is , for lack of a better word , " erect " , and stays that way ! It's dorsal fin is normal , what is going on ? Anyone see this before ???

It has been this way for at least a few hours if that helps ???

 

[Madjamey]

No ideas ???

Can you get a pic and post it please?

I can't get a good shot , it keeps hiding when I get close enough to take a picture. Just imagine when a yellow gets startled and it " flares " it's fins in defense mode, but it's just the bottom fully " erect " !

Dose with Viagra, seek medical attention if it lasts more than 4 hours. (Better add, just kidding.)
