O.k fellow reefers now is the time to chime in. It appears that my daughters tank has gotten a hitch hiker (Asterina Starfish). About 3/8ths of an inch in diameter. Please let me kow the pros and cons of this guy.. Let met preface the story first: She loves the little guy/girl. Her tank is a 30 gallon long with some palys/zoas, kenya trees, GSP, pulsing Xenia nothing of super high value but a pretty tank for her. Will this guy decimate the palys or what? Any advice is very well received. Thanks in advance. Mike
