I don't think NC was suggesting you euthanise her. Just that especially with her lying on her back, she doesn't look great, so try to keep your hopes in check. Keep trying by all means, just be prepared that she might not make it.
You see her more than we do, and when a fish is still eating, it's still fighting, and have seen fish recover even when they looked worse, so she still has a chance.
But why were you trying to net her? That's only going to cause additional stress that she really doesn't need right now.
I will definitely try my best to nurse her back to healthy state.
I was thinking of quarantining her but abandoned that idea as from her evading looks like she’s stressed.
Water parameters better with Nitrate lower now.
0 Ammonia 0 Nitrite 15ppm Nitrate.
Will test water daily and do 25% change everyday.
I’m hoping she recovers soon.
Ive spent 5 hours today doing the water change and giving the filters a good clean. The pipes were filthy so gave them good rinse.
She seems to be happier after the water change, not seen her on belly yet so finger crossed
