I noticed coresean has a little "white patch" on her head right before her dorsal fin, it's been there now for 2 days. She seems totally fine, I managed to get a picture of it. I don't know if it's anything serious, it's not fuzy or anything. Looks like she might just have scraped a scale. I'll keep watching it carefully but if it does look like anything bad to you, please let me know. thanks
In the first pic it's blurry but you can see how noticable it is, and in the second one you can see it a bit more clearly just not as white.
