Here is a couple pictures of my Zonatums. There color has changed. I first thought that another fish was picking off the scales. The fish has no body wounds and eats very well. Has anyone seen or can explain this change in color. I have 4 total. One has turned completely pink. The other as you can see is losing his color. The other 2 a perfectly fine and seem to have paired up some, at least they are always together.
