I went on the hunt last night to figure out what was attacking my Zoa's. They are all now closed shut. While looking over the colony I noticed what I think were nudibranch's. The body was a grey color and the spikes were colored bright green. I counted 6 believe it or not. So I grabbed them and pulled them out. Wrong thing to do. They all dissapeared and now I fear that my other colony in the back will come under attack soon. How do you remove these guys? They are all very small and once I get into the tank there is no way to get a hold of them. I tried tweezers on the one I spotted still in the tank after this.
To make matters worse I began dissecting the rock to see if there were any I could save. I ran across a few other things to my surprize. I removed a few LARGE bristle worms. One being longer than 12" and good sized. I also came across a few brown worms. They don't come out of the rock at all. They slink in and out of themselves like those toys that you roll through your hands and it's filled with jell and usually some glitter. I also found a small brittle star that I'm not sure isn't green. He doesn't have the bands on him like the other ones I've seen in the tank. I also found a crab who is missing one of his claws but even though his small size I can tell they are pointed and not a good sign. I also came across a few sand dollar like stars. I have no idea if they are good or bad? Anyone with a possible id. I don't want to kill anything that deserves life in a reef tank. The tops of them are bumpy and they have three longer arms and three shorter ones. The one sticking to the glass sort of has the appearance of a marajuana plant leaf.
Any thoughts, id's or possible comments are welcome. Thanks, Angie
