Hello rsxs1212, I mean absolutely no harm or disrespect, but you are doing even more harm to your colonies by moving them around. Even if they expand more once you move them. Zoanthids do not like to be moved around. Relocating and persistent repositioning with stunt or dramatically decrease the growth of said colony.
Instead, I would focus on the root cause of your ongoing problem. Zoathinds can and will periodically close up for a few days to 10 days, and yes, this is normal. It is documented as a means of cleaning themselves externally. What makes this forum such an asset is that one can come here and find a wealth of knowledge and documentaion on zoa keeping.
You could possible have a number of issues.
1. A zoa eating worm.
2. Sundials.
3. A fish that is nipping at them.
4. An invert doing the same.
5. Unstable or flucuating parameters.
6. Large Emerald Crabs or a Sally Lightfoot. Both can and wil
eat, kill and cause polyp retraction
Are you experiencing any die off?
Any polyp detachment?
Holes in your colonies with emtpy spaces?
Try this
1. Do a well aerated % 15 to % 20 water change
2. Reset your salinity precisely
3. Start using Vitamins and ammino acids
4. Remove a total of 4 colonies, one from each from each region
of your tank that are retracting and do a fresh water dip.
Choose a zoa colony and not a Palythoa.
5. Before dipping, use a very large turkey baster or a power
head and clean off your entire reef. Do this before the
water change. You will dislodge lots of sediment.
6. Clean off your bulbs with a warm water towel or alcohol wipes.
7. Check for stray voltage.
8. After you have done all of this, run your actinics only for todays.
That is, your normal photoperiod and not for 48 hours.
Note anything in your dip water or changes.
Hope this helps, Mucho Reef
