I have a Lineatus Wrrase that I bought about 2 weeks ago. He is still in qt. He arrived very healthy but he now has an open wound on the top of his body behind the eyes but in front of the top fin. I think he was rubbing it on the eggcrate that I use to separate fish in QT. I fixed it to where it would not be able to rub on it anymore and I started to treat with melafix since last thursday evening. It seems to be getting worse. I don't know how to get my pics on the web to show you what it looks like...Call me pc illerate. It does not look like parasites or anything like that. It simply looks like an open wound. Like as if he has been rubbing it on something as I suspected. How do you suggest I treat it?
