I just made and somehow deleted a thread so making again a new one.
I bought two months ago 2 black ghost knife fishes. One of them is all black other had a silver/white stain. It is a dominating one. Now the stain has enlarged. Its silver/white from the head to the middle of the body. What can that be?
