YWG sickly behavior

[dejaknu]

My YWG is normally very adventurous but hasn't been for the last two days. Yesterday, I got a small torch coral, my first coral. After putting it in the tank, I didn't see my YWG all day but I didn't think it was too strange.

Today, he is out but has been sitting in a weird way, on one side. He ate 1 pellet (normally eats two) and always goes for mysis. I just tried mysis and he is trying to swim after them but can't catch any in the water. He seems to swim poorly. He is usually very agile and loves chasing after the shrimp.

He's also doing this yawning thing I only rarely saw him do before.

Is there any possible way the coral is doing something even though I haven't seen them touch? I also dipped the coral but I dipped it in unmedicated tank water before adding it to the tank (as per LFS and bottle instructions).

Params as of yesterday before adding the coral:

Nitrate/Nitrite/Ammonia/Phosphate: 0
Ph: 8.3-8.4
Ca: 420-430
Dkh: 8.3
Salinity: 1.025
Temp: 79

It has been around 24 hours since taking those. YWG is about 2 months old and has been perfectly fine since then.

Any help appreciated!

Anything on the fish itself? Mine disappears for a day or two sometimes, I've never heard of a torch coral stinging a fish like that but it could be possible

No, nothing I noticed anyway. It's been hard to see one of his sides. It's mostly the strange gait that's making me worry.

Sorry what do you mean by gait?

Sorry, just the way he is moving and sitting. It's like he's about to fall over on his side.

By the sounds its very possible he could have been stung
