Worry about your own tank Daniella. I dont require your advice. You don't know my system so drop it. Yawn.

Stay on topic.

Those "spikes" are not good and more than enough to make zoanthids melt.

That for me is making more sense for zoanthids melting than asterina starfish. I too have tons of them, and at the end they were not responsible for the melting. After I got my alkalinity stable with dosing a little bit each hour, the melting stopped, although I still have as many asterinas and yes they do crawl on my polyps but the polyps open when the starfish is gone. When I see them on my frag I throw them away just in case. Zoanthids are so sensite, it is unbeleivable. I dosed "Kent Iron and magnaneese" a litle bit less than what is recommanded on the bottle and instantly my magicians closed. It took them 2 weeks of TLC to recover from that! They shriveled so much that I was sure they would melt. All that was left was a tiny shaft with melted tentacles. I was dosing this for my alveopora and goniopora. Next time I will dose a very small quantity and more often. Lesson learned. I know it's the product because the reaction from it was immediate and long lasting. I had to do 2 30% water change to bring them back to health.

If you have that many asterinas and you think they are doing dammage, maybe you should get an harlequin shrimp? They only eat starfish. After your asterinas are gone you would have to feed it a starfish eavery 2 weeks or sell it.

Sorry again for the hijack
