Hey guys, Ive had a colony of Zoa's for about 2 months now, and although they are growing new polyps, there are a ton that are dying off. I started with a rock that had 3 color morphs and now almost one entire color morph died off. I have inspected the colony and I can only see two possible things that might be the problem. 1. I had 2 of these little guys on the rock [IMG]http://img.photobucket.com/albums/v290/ilyad/Tank%20pictures/IMG_1331.jpg[/IMG] It split into 2 and last night and today I caught and pulled both of them and they are no longer in the tank and 2. This random white thing between and on the polyps [IMG]http://img.photobucket.com/albums/v290/ilyad/Tank%20pictures/IMG_1543.jpg[/IMG] Here is the close up (note the Y shaped white thing above the polyp reflecting blue) [IMG]http://img.photobucket.com/albums/v290/ilyad/Tank%20pictures/IMG_1543_2.jpg[/IMG] Here is another angle [IMG]http://img.photobucket.com/albums/v290/ilyad/Tank%20pictures/IMG_1544.jpg[/IMG] [IMG]http://img.photobucket.com/albums/v290/ilyad/Tank%20pictures/IMG_1544_2.jpg[/IMG] And you can see it on the side of another polyp as well [IMG]http://img.photobucket.com/albums/v290/ilyad/Tank%20pictures/IMG_1553.jpg[/IMG] Close Up [IMG]http://img.photobucket.com/albums/v290/ilyad/Tank%20pictures/IMG_1553_2.jpg[/IMG] In the tank [IMG]http://img.photobucket.com/albums/v290/ilyad/Tank%20pictures/IMG_1555.jpg[/IMG] Are those white tube thingies whats causing the problem? Or was it the star? Also, if you notice anything in the pictures that might be the problem, please let me know. Thank you in advance
