Can I do sth for this guppy?
I found this guppy at the bottom of my tank today, floating head-down. She was still swimming yesterday night, I can't remember if I saw her this morning. For the past 2 days I thought she was a little slow, so I kept an eye on her, but she kept feeding with the rest. My water parameters were checked just now and everything there seems perfectly okay, so are the rest of the fish and the snails.
She is relatively new but not so new I would think it stress from moving.
Rn she is in the small cup while I wait for the extra aquarium to acclimate to room temperature. She's lying with her head on the floor and the rest lightly raised, sometimes on her side, sometimes on her back.
The whole fish population has only been with me for ~3 weeks, and I haven't seen any other signs of disease except for the occasional a bit pale or too long poop that made me contemplate a parasite treatment and she especially has a very flat tummy compared to my other females, but again, no one has been off so far so I kept a close eye to let the babies I have grow a bit more beforehand.
Now I am wondering if there is anything I might be overlooking in terms of causes and if parasite treatment is recommended. I honestly don't think she will make it which is a shame bc she is really pretty but maybe the biggest favour I could do her would be euthanasia?
