Hi gents, recently ive been loosing the odd sps slowly. When i got home today i noticed a shortcake frag that i had placed down a few weeks ago had bleached out totaly and it was fine yesterday. Crawling away from the area was a 2cm little star fish, near the other corals that were slowly going i found another then i found one on a coral that was partly gone. Could the starfish be the reason for this? Water chemistry is fine and nothing seems out of wack. What do you lot think?
