Clown fish potentially dying

[ibinyth]

My ocellaris clownfish who was recently moved into my Nuvo 10 (two weeks) as I tore down my old tank isn't looking too good... I came home to find him laying in the sand breathing heavily he can still move around a fair bit but 90% of the time he's been laying in the sand away from the flow... Coloring looks normal... I did a 50% water change and he moved a little more.. then he started laying on top of my mp10 intentionally it seems like.. that and he kept rubbing up against the glass... As of this moment he's back to laying in the sand... This happened within a few hours while I was at work as he was all over the place when I left as usual... I have no way of testing the water.. I'm waiting on a new test kit to come in the mail from BRS... I'm fairly certain I'll lose the little guy which is sad due to the fact he was one of my first fish and he's been around for a while... I was just wondering if anyone had any input on what could be wrong

Is this a newly set up tank? If so there could be ammonia. If you currently have test kits take a sample to an LFS to get tested.
