Less than a year ago,I bought a 55 gallon tank. I bought 50 lbs. of premium liverock and set up a DSB. I didn't know anything when I started and was not very smart with some of my livestock purchases. After a couple months I bought a bubble tip anemone and a colt coral. The anemone was the size of a half dollar, colt was small too. I got on these boards and I have tried to learn as much as I can to keep the anemone alive. Well its alive and growing out of control along with the colt and the other corals. I knew they would grow but its nuts. Bought 1 stalk of xenia now its spread over entire rock with at least 10 stalks. I want to upgrade to a 75 for its width. Im real worried this will be to small in a few months. Point is buy tiny frags because some corals and animals grow like weeds.
