I got a test kit for ammonia and it's fine I havent tested for any thing else. He almost ate today but despised not to. I had some krill on a stick and he went to eat it and couldn't get it off the stick. After like 2 tries he gave up. I then put the krill in the sand. He knocked it out of the sand with his face, so Idk. He is still breathing heavy. But better than before.
