I have a 55 gal. fresh water tank at this time, now I want to get a salt water tank. I want this new tank to be in the 150 gal. to 175 gal. size range, (I want a 200 gal. but don't think the wife will go for it ). I have started to read some on line about salt water tanks and come to the conclusion that I have a lot more reading to do,lol. I have seen pictures on line of reef, live rock and open water tanks, and everything I read says this is the first choice I have to make, what kind of tank I want. I like the reef and live rock tanks but in the pictures I have seen the tanks space is taken up a lot by the number of rocks and corals. I want a salt water tank that will allow me to get the most variety of fish in the tank as possible , the fish are what I like. Is there a happy balance for me, or do I need a 1,000 gal. tank, just kidding.
