hello i have had freshwater tanks for about ten or so years. Have always kept chiclids for their beutiful colors, As you all know most of the colorful fish are also the most aggresive. So i have decided to take the plunge into a sw tank. I have read some things about them and have decided to start a reef tank. I have a 55 gal tank, Really leaning towards a sand bottom, like i said dont know much about the percs of the diff types. Also some realitivly cheap coarl to buy to get things up and running.
