Hey everyone. My chalice developed a small pale spot with a small opening and was wondering if anyone knows what it is. I’m between a small bleached area, a pest, or possible a new mouth. This picture is after I fed it so I think what is coming out of it is residual food. Besides from this spot it’s doing great and growing

Here are some better pictures. I do hope it’s a new mouth but it’s a bit pale and flattening in that spot. I’m also thinking it might have gotten stung when I was moving some other frags around. I’m planning to just keep a close eye on it and if it gets worse I’ll dip and move to lower light. Other than that one patch it’s puffing up nicely and there’s nothing wrong with it at the edges
 
Bleach wouldn’t be such a small area. It will turn back to normal if water is stable.
