Is he the bain of my zoo problems?

it looks more like a collinista snail to me, which are harmless algae grazers.

Doesn't look like one to me, and I've seen my share!

+1 collinista
beneficial and that one looks full grown.

Have you checked for nudis or spiders.

If indeed it is a collinista snail, they do multiply quickly. I had some in my 34 gallon that came on some rock and by the time I shut it down they were everywhere!

thanks guys

For the life of me, I can't grow zoos.
I used to be able to. Had a fanatasic zoo garden.
I thought it was the summer heat that wiped them out 2 years ago, along with my lps.
I am re-establishing my lps.
I've tried a few time to re-establish with frags, with no luck. They seem to last only a few days, then dissapear.

Would urchins bother them? Could it be my tuxedo, who I've seen over the frrags?

some urchins do develop a taste for coral. You usually see a path eaten through your zoo garden.

I would shine a red light at night on them and see if you can find a culprit. I had a eunicid (sp?) worm eating one of my colonies.

peanut worms? I have tons of those. Are they my problem?

peanut worms are ok
