Well it wasn't there when i originally posted and it most likely isn't caused from them locking lips as they never do that. I did some more searching about the swollen lips and found out it has lip fibroma and is common in some angelfish. The only way to rid it of this is supposedly surgery. He is still eating fine andam not going to do this so called surgery bit. I am treating the tank for fungus and everything should clear up. I think he got the fungus from one of my whisker shrimp as i found one dead when doing a water change tonight covered in fungus. It is the only thing that makes sense. Thanks!
