Lyre Tail Is Upside Down :(

[AmtotheBurr]

My lyretail I recently bought cannot stay upright and even though it's been 24 hours and she's still breathing, I don't think she's going to make it.
Is there salt or anything I can do to try and fix her and get her upright?
Should I just euthanize her and how would I do that?

I tried to keep her in the net to help her stay upright and to keep the snails from eating her alive if she sits on the bottom. They did stay off of her this way but I haven't seen progress today and don't know if there's something that can help her recover

Does the fish move at all? And does it still eat?
 
When reading that he can't swim properly, I would think that it is a Swimmbladder problem. A remedy of this is feeding him a pea. However, the picture would suggest that he doesn't swim at all. Which is strange and gives me reasons to doubt my idea about a swimmbladder problem.
 
Some others might have better ideas.

Much more information is needed. Without knowing water parameters, it's very hard to diagnose a possible cause and therefore even harder to offer up any treatment.
 
Check out this sticky post for the information that is needed. http/www.fishforums.net/index.php?/topic/422952-start-here-with-your-emergency/

He passed away. He wasn't swimming or moving at all but stayed alive for over a day like that. He was acting really sporadic in the store and was going up and down repeatedly really fast and I thought he was just an excitable fish since he was the only one acting like that. So unfortunately I think I may of just gotten a bad fish
