I am sorry for asking again, but can I ask for some help again? Today I just notice something off from my leopard bush fish. Around its snout, there are some white patch that is not cottonlike but more like a lesion (red circle in the photo). But there are also some black dot around the margin of the lower jaw (blue circle in the photo). Yesterday I just happened to change 30% of my tank water as usual. But yesterday I add a tad of antibiotic for my rainbow shark that lose its skin as a preventive action since I am kinda afraid it will get infected by something.

Judging from the pics (sorry for the low quality, this is the best my phone could take while zooming in), what is wrong with my fish and what should I do about it? At first, I thought maybe it is just some particles from the sand that got stuck in its mouth while taking the food from there

Looks like it’s a scrape more than mouth rot. Just IMO.
