help with zoos

[CD]

wendy mine is white too, do you think that could be it. I have tried to rip it off but it is impossible

Definitely - the zoa rock we have has lost over half the polyps due to this darn sponge. Thankfully, it wasn't a super colorful rock and was inexpensive, but I still wanted to save them if I could. Toughest sponge I've ever seen...LOL :roll

I am going to try to take it all off today. I love my zoos and those are my favorite. I will let you know on the progress

Thanks Joshua for your input. I will do it immediately.

I had zoos on one rock that did not open up and the rest would open. I inspected the rocks several times over and didn't see anything. I came by one night at midnight and turned on the lights and right on top of the zoos was a large sun dial snail! How could I miss it in all my inspections? I took the rest of the zoos out of the tank and left the ones it was on in the tank and after a few weeks the sundial ate all the zoos in the tank.

I still have plenty of zoos in my main tank but my temporary tanks have been cleaned of zoos.

Keep checking your zoos and try looking at them at night.

Sponges can have some crazy toxins in them, so it's not surprising that nearby zoas might be effected.

I didn't really realize that until you said this Joshua! I've never done a lot of extensive research on sponges, as we've never "intentionally" bought any, but it IS pretty amazing what kind of toxins they can have...even toxins that will cause rashes (and the like) on people's hands that touch them. I guess I've been pretty lucky up to now, as I have touched a few sponges by mistake - I've GOT to be more careful!

OH - BTW - I've got something else growing on another zoa rock...it's kind of soft, and a dark purple-ish black color. The zoas that are on the rock don't seem to be affected, but they are not spreading any either. Looks like some type of encrusting coral, but it *could* be another type of sponge (I guess?). Has anyone had anything that looks like that in their tank?

Thanks Joshua for your input. I will do it immediately

So how are the zoas doing? Were you able to pry that sponge off the rock?
