Thanks for the reply.
Sorry, forgot to post a reply on the params of the water tests last night. PH, ammonia, and Nitrite levels are great. The Nitrate level are high, I performed a water change just over a week ago. I was going to do another one next week. The invertebrates (crabs) do not seam affected with the elevated level of Nitrates.
I have not seen any appetite changes last night after this post. When I get back home, I will re-assess.
I currently only added stress coat. Worried as to what the treatment path should be (fungus, parasite, or bacteria infection (internal/external). I just do not want to diagnose.
I thought that it looked like a pinch mark from a fish. A Luminar Wrasse swims all over the place and hangs out close to the puffer. The Luminar's mouth is about the size of the dark area. I just do not understand why that would affect his appetite. No additional marks or signs of stress, on either the Wrasse or puffer.
