I have a 2 year old female Micky Mouse platy named Mini. I've noticed about 3 weeks ago that she has a blue-greenish spot on her head that has never been there before. For the past two weeks her fins have been clamped down and she's been hiding. I've put some salt in there to relieve stress but it doesnt seem to help. There arent any agressive fish. All of my platies are friendly with eachother and I constantly watch my tank to make sure of that. Does anyone know if the greenish spot has anything to do with her weird behavior? She isn't pregnant either. Please give feedback if you think you have advice! She was my first fish and I'll be very sad if she dies.
