guppy drooping tail

[mistymists]

So I get home from a long day at school and one of my female Guppies is acting funny... It's like she cannot move her tail at all. There's a point on her back where her skin tone gets slightly greyish, and her back tail is acting like a giant weight. She's pretty much just resting at the surface and breathing from the surface too. None of the other fish are acting like this and she was fine around 5pm on the 3rd. Any ideas what could be wrong with her?

Not sure the issue but I had one this week doing the same thing and found it dead yesterday. Hope your luck goes better than mine. Jack

I hope it's not Tetrahymena. It's practically impossible to cure. I'd hit it with formalin/malachite green, and some salt, too, if you're willing.

It died. None of the others seem sick. Everyone is healthly and happy and the only new fish that get added to that tank are the ones the females birth. It's not even at the same house as my other tanks. Strangly it reminds me of a few patients I've cared for in Hospice who for some unknowingly reason go dead from the hip down and then it spreads upwards until they die. She was a pretty old guppy. I could tell that when I bought her.

maybe its back was somehow broken
