Our salt section isnt TOO big...but there are plenty of people that hand out good advice. That being said, I would still recommend reading.
I expected kevin to mention this, but a good place to read pretty much all you want for free (and ask questions) is wet web media ...do a google search for that. Its probably the best collection of fish knowledge on the internet.
That being said, I am a member on
www.reefcentral.com and
www.reef2reef.com reefcentral is HUGE...probably one of the biggest online fish communities. All of these are good places to start.
The books kevin posted are all good. (Based on the ones that I personally have) most of my books though have reef focus, so that might not be what you are looking for.
