Just curious, why are you wanting to start a saltwater tank? If you are new to it, freshwater will be much easier to start. Sorry if this doesn't help.

A general rule is: one inch of fish per gallon. For a 20 gallon tank, you can have a max. of 20 inch-long fish, 10 2-inch-long fish, etc.

That "rule" is so outdated it's not funny. Please do t offer this as advice.

No bad!!!! In a 20g saltwater tank you can fit 3-4 small >3" fish. The inch per gallon rule is a horrid thing. Op are you new to fish keeping or have you had a fw tank?

Well, without knowing what you want to do with the tank I'm not sure what we can do to guide you in the right direction. Fish only tanks are quite different from reef tanks...soft coral are vastly different from SPS corals. You aren't really giving us much to work with.

In terms of fish, you should check out the 'nano section' of liveaquaria. They do a really great job with how many gallons fish need to be healthy and thrive. Once you figure out what fish you can't live without, you can build up from there in terms of what it can live with and so on.

Oh no! I'm so sorry! I've been in the hobby for a while, but all sources I've seen have shown me that rule. Thanks for the enlightenment.

With this kind of attitude I'm surprised anyone will help you. See my previous post. I started to help you... As hank said what kind of tank do you want? What is your aquarium experience? You'll need about 1 lb per gallon of rock (base or live rock) and aragonite based sand. You'll want to use rodi water for the tank or you can buy it from a lfs. I'd run a hob filter (aquaclear 50) with purigen and a phosphate removing media. You'll need powerheads and a refractometer to measure salinity as well as a test kit
