Looks like a wound indeed and these guys will dart into any opening when they see you coming which youve likely seen already. The appearance has an unusual sheen but treatment while it appears to be healing would not be bad to at minimum add Ruby Rally Pro to water for protection and also acquire some Seachem Kanaplex should it go the other way and become infected/raw which will then be treated in a quarantine tank setting.Overnight a white patch has appeared on my tailspot blenny's head. Behaviour seems normal otherwise. My best guess is he somehow scraped himself on the rockwork, or possible aggression from the clown (though I have seen no sign of aggression in daytime). Any thoughts/concerns? If it is just a superficial injury, anything special I can do to help healing?
