My inability to have thriving zoas is driving me insane! I have yet to lose a colony, but the ones I do have will not fully open. 90% of the time they are fully closed and occasionally they'll barely open. They aren't dying, they aren't receding, and I've inspected at night with a flashlight MULTIPLE times and see no nudibranchs, spiders, snails, or any other of the parasites common to zoas.
All my other corals, an assortment of LPS
and softies all look great. Xenia are pumping, Kenya tree stands upright, fiji leather opens fully daily, bubble coral is gorgeous, frogspawn looks better than it has in months (i had to move it back to it's original location), mushrooms are healthy looking, candycane is splitting, GBTA is settled in the bottom portion of the tank, with actual bubble tips
and hasn't moved since it healed (somehow injured it's foot and stayed on the glass in the corner for 2 weeks; it looked like it was torn from foot to mouth, I didn't expect it to make it).
I'm just at a loss on my my zoas won't open. I know they're not getting too much flow, which is the only thing the owner of the LFS
could suggest after drilling me with questions. I'm lucky to actually have a good LFS
for corals. I feel bad for his fish, but his coral tanks are top notch, and he knows his stuff!
What happens when I get a colony is shortly after introduction they will open fully for the next few days, then they gradually open less and less. To test this, I bought a small zoa frag from the LFS
. Exactly what I predicted happened and within the next week they'll probably stay closed.
My parameters are all fine, I don't feel like listing out all the test kit readings but they all fall within the norm. Any advice is greatly appreciated!
