Colony Won't Open Fully

[Tranquil201]

I had this colony for a while and they just stay closed some open others do not. I have complete seperate colony of all green and they are perfect open everyday without problem... Any suggestions here is a photo also. I have moved the colony around the tank trying different spots more light less light nothing seems to make them open fully. My other colony the all green which is sitting at the bottom of the tank not in this photo is open fully and growing without any issues. My tank is 24'' deep. I use Tek Light T5 8 bulb system all ATI bulbs.

If you just put it in the tank give it some time.

If it has been closed for several days, make sure there are no snails, starfish, or nudibranchs climbing on it.

What are your water parameters?

try putting in a spot with hardly any flow for a day and see if it opens up

Any progress with your zoos? The way the colony looks is usually when some sort of pest is in it. Like a nudi, zoa eating worm, or even a bristle worm can irritate them and get them to close up. If you can remove the colony try dipping it in revive or coralrx to see if anything comes off. If you do find nudis make sure you get the EGGS! Good Luck!

This is a great post on reefcentral. Kind of a checklist to go through to see if any are your problem.

I'm going to sip them in coral RX tonight and see and then repeat in a week.
