Wait or Euthanize? Six line wrasse

[t4zalews]

Did a bunch of searching around, looks like my new six line has swim bladder issue. He is literally upside down and just lays on the bottom of the tank all day. I still see his eyes twitching around and he tries to go for food (kind of). He did try to escape, very poorly, when I went to net him to put him in a containment box in the DT.

Should I euthanize him for the better of the tank, or wait to see what happens? Got the six line on Friday.

Everything else in the tank is doing just fine, got 2 clownfish, starfish, assorted crabs and snails.

Do you think he'll pull through? If not then it would be best to just euthanize him.

I'm going to do a big water change tomorrow and see if that helps. I've been non stop reading and sounds like maybe nitrates could cause digestive backup. I've never seen a fish this with it but looking like on the brink of death, they usually have that I'm about to die look. This guy has more of a..what the hell is going on..kind of look.
