New and need help

[nefarious]

Hello everyone,

I am new to both this board and to actually keeping fish alive. My family always had freshwater fish but managed to kill them all.

Anyway, I'm looking at buying a tank and have an opportunity to get a 5 gallon tank with everything except lights for $50. That or I can buy a 20 gallon tank with everything for $100. I don't even know if I'll be able to keep anything alive.

So my question. Since I'd rather spend a little money to begin with and see if i'm a saltwater fish murderer, what fish are recommended for starters with 5 gallon tanks? are there really any fish that can be kept in that small of a tank?

or should i just bite the bullet and go with the 20 gallon tank?

thanks in advance
