i bought some zoo colonies online . i was really busy when they arrived. so i through them in the tank after a quick acclimation. they all opened up that day , but slowly less and less are opening up . the rocks have all different color zoos on them. the ones that are pink and blue are the are the only ones not opening any more .are they dying .they are at the bottom of my tank ,maybe more light? or maybe theres a parasite of some sort on the rocks ? should take them out and dip them if so with what and how. their under t5 lighting and all of my other stuff looks fine . please help me save my zoos.

give them time, zoas can sometimes take a while to open fully. as long as they're not oozing or anything they should be fine. you would be surprised how resilient they are. if you suspect a parasite then give them a quick dip in RO/DI or iodine solution. just dont keep touching and moving them, the more you do the longer it will take for them to settle in.

There will be more people that look here that have and love zoas.
Take a look at the locked threads on the top of the page there is one of preditors and irrtants. look through it and see if there might be something like these roaming in your tank.

Pinks usually do take a little longer to open then others depending on what theya re. Are they a tight mat type? If they did already open and then closed it would be good to do a dip and look them over closely for nudis and such. 1 safe way to dip is to place them in a white bucket of F/W that is the same temp and ph that has a couple drops of lugols iodine and a drop of flatworm exit for 3-5 minutes and then splash them near the surface for a little bit, maybe 30 seconds to knock anything dead off of them.
This is the norm dip treatment for what I have seen going around.
I have dipped mine in pure F/W, F/W with iodine and flatworm exit and all have seemed to work with no zoa losses.
If you don't do a dip upon getting new zoas you really shouldn't be putting them in with your existing zoas. Nudis can spread fast and they lay average of 50 eggs that they can hide really well.

iodine is really a bio-security measure... it will remove / kill any parasites living on the coral. just don't dip anemones or clams.
