Ryan, have you had any aquariums before, FW
? From your name it looks like you are into Yellow Tangs. I understand you aren't ready for a tank large enough to house one, but going small isn't the best way. It is easier (assuming you can afford all the equipment) to have a 125G than it is a 10G. First off, you'll spend $5 - $10 on sand. maybe a little more just to get the LR
. You'll want to spend $50 on a bucket of salt. WIth a tank that size you'll be doing a lot of water changes. Right there you are already at $75. No tank, lights, heater, powerheads. I love this hobby, but it isn't a cheap one. You'll find in the long run, if you ignore us and just jump into it, you'll spend even more money on replacing fish, dealing with algae...etc.
You can find some good deals on craigslist, but if this is your first, 30G minimum. Do any of your friends or family have a tank? There also might be a local reef club in your area that can help with finding cheaper setups. $75 won't cut it though..not for the long run at least.
