Agreed ^^ I don't like that website at all. It is presented like a scientific paper, but it hasn't been published (as far as I can see), and this McLaren guy has never published anything. So even though he cites lots of references, the way he presents his argument hasn't been peer-reviewed, which basically means he can say anything he likes.
In scientific terms, your findings/observations don't mean squat unless someone else in your field but not involved with your research has looked at your results and thinks they are reasonable.
Having said that, I think there's nothing wrong with photonic therapy and there's a fair bit of science behind it, but this guy isn't helping with his crappy pseudoscience.
As for the red fish - you can get a green fluorescent protein out of a certain jellyfish and pretty much put it into anything you like:
Here it is in a mouse

And this is what you can do if you're a real nerd and you tinker with the fluorescent gene to make it glow in other colours, you get a range of colours all expressed by different bacteria

That's right, fluoro stuff is fun

*nerd*
