OK I just got done tearing my rock apart to get the damsels out of my tank, sad to see them go but they had to find a new home. I now have a very nice coral beauty , YAY! But i just wanted to say to any newbies such as myself that maybe the raw shrimp in the tank is a better way to get the cycle started. No fun at all tearing apart your tank to get these very fast lil guys out.
