here is another pic of the zoa's... is this white fungus? how should i get rid of it? i did a FW dip this morning and thats when the crap poped out. i found a large nudi looking bug on my other orange polyps.... ruff week on the reef all in all..

Anyone have any idea?

I always say "if in doubt, throw it out" (this works for items in your fridge and unknows in a tank, lol)

 

[smallreef]

Its not really clear enough to see if it has hairy leggs (my personal determination of BAD crabs, lol) but still if he was free and a hitchiker id just get rid of him...

 

[lubeck]

I threw him in my sump and it does have hairy legs

What about the zoa pic? Is it pox? Im going to do an iodine dip. Will that help?

If I remember right you would do good to dip in Iodine, just follow the instructions and dont let it be dipped for too long, also as I recall, pox tend to be all over the polyps and remind me of ick. Unfortunately, I can not really tell from the picture, is that glare off the zoanthid slime or are those the spots? The crab on the other hand looks like an emerald crab to me, that's just judging by the pic, so keep an eye on him but he is probably okay. A general rule about crabs, if they have black tipped pincers, then toss 'em!
