What is this guy??

[Surfintx2004]

Found him messing with my zoas. wicked looking but what is he? Good or Bad? He moves like a snail but I feel like his intentions are different.

Looks like a bad nudibranch. I'd get rid of it and check your zoas for eggs.

zoa munching nudi. Up to no good. You may want to remove the zoa colony(ies), then scrub, shake, swish, and dip them.

+1 on zoa eating nudi.
Get rid of them ASAP!

 

[Surfintx2004]

thanks for the quick response. the issue I have is that the colony is on a big rock with other coral on it. I'll keep an eye out for others with suction ready.

Yep no bueno!!!

Flat worm exit made by salifert does the trick. Use 1 drop per gallon and follow the directions otherwise. It will definitely take more than 1 treatment because it will not kill the eggs.

 

[nickg]

Let us know if you see any more

When I had mine I used flatworm exit at 2 drops per gallon. Seemed to kill the tiny tiny newly hatched ones,but was in effective against the adults. Found some alive the day after treatment. Found that a blue flashlight (automotive stores have them for leak detection in ac system) and one of Julian springs things was the most effective for me. Would just suck em out after lights out. They glow the same color as the zoas they are eating.

That's strange. How long did you wait before running carbon? I had some that were at least 1/4" long and it killed them.

Ran it all day with no luck. I found being diligent about checking for them after lights out worked best.

Dipping in a peroxide solution kills'em dead. I got rid of mine after dipping all my zoas 3 seperate times approx one week apart.

 

[davejep]

Not an option when you have a tank full of zoa's unfortunately.

dip dip dip

I had some in my tank. I got rid of them by sucking them off of the zoas.
