cichlid help in the Seattle area

Hi! I am looking for help in locating somewhere in Seattle where I can
obtain a large fish tank. next year I am wanting to start a cichlid tank.
I want one that is over 75 gallons. I live in the middle part of the state
of Washington, but there really aren't many places here to get any good
deals, so I am willing to drive a few hours to get what I need.

I currently keep goldfish and have had much success with them. cichlids
really fascinate me and I've always wanted to have some. I don't plan on
starting until I do much more research on them (early next year). and I
know it will take a while for me to get the tank cycled and the pH correct
once I do begin this journey. I am leaning toward the African variety and I
am also leaning toward the ones that average about 4" - 6" inches in length.

any sites or books that someone can recommend is very much appreciated.
thanks in advance for reading this and for any help you might be able to
provide

best regards,
connie
