Trying to find out if this is going to eat my zoas or may e just be harmless. Very bright yellow in this little guy and the only one I've seen in my tank.

Once they start feeding they will change into the color of your zoas very freaky. I had them once in my tank took some time to get them all and they reproduce quickly. I used a little air line and sucked them all out good luck.......

I took the frag out and pulled all of them off with tweezers. The consequences of not dipping your coral man...

I dip all my corals but this little guy must have made it through. I checked all other zoas and they seem fine. Maybe just a single random one.

yeah get him out of there and keep an eye out for any friends he may have come with. sometimes they can make it through the dips

I've not heard of this yet, how does the color change?

Eggs will survive dips. So even dipping isn’t a sure fire way to prevent these nasties from getting in.

I took him out immediately even before I posted this thread and threw a random zoa I had floating around the tank (colony break off). Sure enough he went straight for it. I will have to keep a close eye from now on but I tried to inspect the ones I have but when you are talking about 30-50 frags and multiple colonies its a needle in a haystack lol. Thank you everyone for the quick responses. Always appreciate the help.
