Hi everyone,
I noticed this wound today on my new mandarin fish, which I introduced four days ago. I don’t recall seeing it when I first added him to the tank, but I might be wrong. Since his introduction, he’s been having compatibility issues with a smaller Royal Gramma that I often see acting aggressively toward him whenever the mandarin approaches its territory — and this happens repeatedly.
Could this be a bite mark or something else?
Is it something to worry about?
Thanks in advance!
