some pBass questions

I have a couple of questions.

1. I've read in several threads that indicates pellet feeding brings out better colors in pBass? Is this true and why? If they do not take pellets is there a way to bring out the same level of colors (may be by giving a variety of fish meat types?)

2. What is ich? How do I identify it? Is there a comprehensive thread on this?

He,he. Where I live, fish fillets is the cheapest. I mean there are cheaper pellets but probably garbage quality and stuff like Hikari would cost a lot. That is why I was wondering whether I could stick with fish fillets (may be 10 varieties) and still get the optimum colors.
I live in a tropical country, so I won't have to worry about ich probably?

Hikari Carnivore sticks better than Natural food? Is that the only thing you feed?
