Zoos Not Spreading?!?

Without getting to crazy on the subject, what would be the cause of this coral not spreading on to neighboring rocks??? Ive had zoos for a year now without any spreading goin on, but they are healthier than ever...Running combo PC & T5 lights...Supplimenting trace elements as well on occasion....

All water paramaters have been in check for some time now and ive had other corals attach to rockwork just not zoos...

Healthy zoanthids spread onto neighboring surfaces. Some even incorporate sand into their bases if no 'solid' substrate is available. They may not be as healthy as you think.

Post a picture of a sample frag in your tank for more precise information.

Zoos

I'm building a zoanthid tank and have been studying them non stop lately. Here's some of what I've managed to confirm from various sources:

Different zoanthids require different amounts of light and grow at different rates due to photosynthetic production rates. In addition to normal water parameters being in check, zoas require iodine and strontium in order to grow and reproduce, in a smaller tank, regular water changes with quality salt should maintain the level of these trace elements, however infrequent water changes or larger tanks may require the addition of these elements to maintain acceptable levels for zoanthid growth.

Here are a few things you can try:
1. Check your bulbs and replace if necessary
2. Move your zoas to provide more light (contrary to popular belief, zoas are not all low light corals even though they're hardy enough to survive low light conditions)
3. Test your iodine and strontium levels and make sure they're acceptable. Iodine is found at 0.06ppm in seawater and can be slightly higher to promote zoanthid growth, strontium is fount at 8ppm

Let me know if this helps
If none of this works... give your zoas to me and try a different type of coral... lol

I agree wholeheartedly with digital. I have zoos in my 75g that all spread at different rates. I also have zoos that are spreading prolifically on my sandbed, like Dean said.

Some of my zoo's don't spread at all but are open and look healthy (same tank as all the others mentioned above).

Try moving them around, might help.
