Is this guppy sick?

[targetfish]

Hey everyone,
Recently purchased some guppies, this one specifically I noticed looked a bit... off. Skinnier than the rest of them, even after being fed, gills kind of red and open? Could be her light colour, not sure. I'm thinking gill flukes and worms? But I have never had to deal with disease before. Maybe I'm being paranoid, maybe she is fine, but I guess I'm just trying to err on the side of caution. She's quarantined by herself for now. I want to get her treated ASAP so that she doesn't have to stay stressed and can go into the community tank with the other guppies. Apologies for the photo quality, active fish are a nightmare to take pics of lol

A bump, I really don't want to keep her quarantined longer than she needs to be while I wait for answers, sorry

How long have you had this fish? How many did you buy at once?
The fish may just need a ltle time to grow large enough to be able to get a fair share a food from the group. If the hospital tank is heated,and filtered, it should be fine for a couple of weeks while you feed extra good foods.

I purchased five of them two days ago. Yes, heated and filtered. She actually got rounder since, she looked completely normal so I did end up putting her back and I'm keeping an eye on her, I gave her colour enhancing bug bites and daphnia

Thats great news! One thing to add, if you want, you can feed a small amount 3-4 times a day for a while, At least untill she grows up a little, like you would feed fry, just make sure to do plenty of water changes snd vacuum uneaten food.
