Is it time to euthanise my tetra?

[Freyfish]

I have had two of my neons die suddenly and a third has been very sick for a week. I’ve treated him for everything I could think of but he’s still isolated, a bit bloated, colour faded and constantly gulping. I feel terrible that it’s suffering and think the best thing to do would be to euthanise him. I’ve not had to do it before does anyone have advice on the kindest way to do so? Thanks

Do you have a picture of this fish?

These are the best I can get- he’s been hiding at the back of the tank near the heater for a few days

Eyes a bit swollen, doesn't look a lot wrong with her other than she's full of eggs.

Feed with Garlic enriched foods or a course of API Melafix

Oh really? I’ve tried feeding her a garlic pea but she won’t eat anything, she’s very pale in colour compared to the others and hasn’t moved for days- she was incredibly bloated and now looks quite skinny. Shes also really gasping, I’m not sure she’s long for the tank

Try this...

Fading of colour, white patches under the skin, distorted shape, loss of appetite... all classic symptoms of Neon Tetra Disease, which is incurable.

The quickest method of euthanasia is to quickly take the fish out of water and squash it. Failing that, Clove Oil.

I thought it might be

If it is Neon Tetra Disease, somewhat difficult to tell from the images you've posted, you need to keep an eye on your other fish as parasite will spread and can effect Cichlids, Rasboras, Barbs, and Danios.
