Ok So about a month back I found a pretty big Asterina Star Fish and pulled him out in case he went rouge and started eating my corals. Anyways I Figured there would be more couse no way theres just one. Last couple weeks iv ben noticing my Coraline algea Disapering and looks like its ben eaten just like the spot where I got the Asterina from last time. After some really close inspection I noticed a bunch of small asteria. So I took out the Tons and started pulling them out. I got about 20 to 25 out really small. They where all over my rocks eating my coralline. I Started to look at my corals to make sure none had stars on them and im clear lol. Might look into getting a harlequin shrimp to take care of these guys. Actually now that im reading it seems these guys eat all sea stars ???? Will they eat my linkia ???? Might have to just keep removing these guys when I see them.
