anybody here raise Bettas? I need 411...

just got one and don't know anything.
RedRed seems pretty hardy.
hasn't died yet after one week and a transfer to new tank. how much should he eat?
I got a tiny packet with the starter kit and I still have lots left.
What are the signs of a fish in distress?
Everything seems OK. Can I add any other fish?

I never liked fish before.
"What a dumb pet," I used to think.
But now I am intrigued and I can see why there are "fish people".
