White patch on male Dalmatian molly's head.

My molly has a white patch on his head. It was black before but after this morning I found him stuck behind the filter. He currently has swim bladder disease so I figured that's why he got stuck. He got stuck between the filter and heater so I don't know if it's a burn or a disease. I don't think it is Ich because the patch is quite large. Can someone let me know if it's a disease or if I should treat it?

Could you make a photo of him that shows that white patch?

It’s not exactly white anymore. But it wasn’t like this before. The patch was lighter this morning.

And my other male yellow molly has a pink patch that wasn’t there before. (Molly fish in the middle). He also likes to hang out near the heater so is it a burn?

First, black mollies (no matter Poecilia sphenops, Poecilia velifera, Poecilia latipinna or other types of mollies with a black appearance) "can" show white spots at any time. Same goes for marble and dalmation mollies. I wouldn't be worried about it.
The pale spot on the head of one of the orange mollies could be something different but could also be the same as with the black one. Each single spot of the skin is usually filled with a concentration of color cells (chromatophores). While aging, the concentration can become less (this means that on certain areas of the skin, the denisty of color cells will become less. That's a total normal thing. Buit it won't happen with every individual molly.
