Circle or crescent spots on Foxface

[IslandReefer]

Just an addon to what Deb said, my foxface can be bright yellow to a mottled grey with spots....very fast..depending on mood ,stress....
"Oscar" is also a pig, and is constantly scuffing himself hiding and playing with the Tang (Felix LoL)...I used to worry but he heals very well...even a good scuff (black or white spot etc) will heal in 2-3 days.
Personally , I think removing fish to treat anything drastically reduces there immune response ( macrophage cellular) for days....so the choice is to treat/medicate with a comprimised immune system or let him heal and add a little garlic to steady your nerves.
my 2 cents ....GOOOOOd Reeeeefing!!!!!!!
