Has anyone seen this before and can advise what is wrong and how to treat? Many thanks Nigel mchughn 2011-10-16 http://forum.aqua-fish.net/?topic=wagtail-platy-question-#2 How large is your tank? Isn't it possible that other fish harassed the injured one? Antifungal medicaments can be used as they prevent the fish from being infected. jan 2011-10-19
