I don't know if the scars will heal. It's a beautiful fish for sure. Just pointing out to another what the blemish was on this fish. Now if the HLLE will progress, I don't know. It can be stopped. But some scars just remain.Could be, but doesn’t look that way to me. I’ve gotten blemishes from them before and I’ve never gotten a fish with later like erosion. And if he does have it, I still don’t really care. I’m confident I can reduce stress enough for him to live a long life!
