Polyps won't open
2 of my corals haven't been opening in the last 4 days, a star polyp and a flower pot (goniopora lobata ). This happened after a water change and a feeding. I feed them and my other corals oyster feast. I've been feeding with the oyster feast, rotifers and phyto plex a few time week with out any problems for about a month now. All of my tests are where they should be,PH: 8-8.2; ammonia: 0; nitrite: 0; nitrate: 0-5; KH: 179; calcium: 480; PO3: 0, salinty: 1.024. I gave them a bath in coral Rx just in case. All the other corals look ok, anything I might be missing?

give it a few more days, especially if you just dipped that goniopora. try not to touch the goniopora. they are sensitive. put it in a medium flow area for now and leave it be.
the corals are probably adjusting from being dipped. just make sure while the polyps are retracted it isn't getting pounded on by the flow

I actually dip them after they wouldnt open...I had some nudibranchs on some of my zoas a few weeks ago...thought maybe some type of parasite was on them

Agree with joemelo.... give them a couple of days and they will probably bounce back. was the water change the only change you made in the tank? no flow adjustment,no lighting change, etc?

as mentioned goni's are very fragile/ sensitive corals....most have little to no luck keeping them...leave it alone for a bit and see what happens.. was the water parameters of the WC water the same as the tank water? a sharp drop/spike in pH, salinity or alkalinity will often cause corals to recede... how old is your tank? dont worry about the star polyps they will do that from time to time...i have had them close up for weeks on end. |
