How big is the tank hes in now?
Just did the water change. About 40%. I have been checking the ammonia and nitrite levels and both seem to be at 0. Is this ok or should I be finding some levels of either?
Here's a picture of the little fella about an hour after the water change. He was just swimming around.

what are the dims (dimensions)

Is the tank cycled? Or are you cycling it with him in there?

Hes fine just give it some time; also the lighting looks a little different (much brighter in your tank)
That would be why your water tests are showing zeros, I did the same thing as you and my tank is now cycled, just monitor the water parameters and he will be fine, nice looking fish btw.
