We (husband and I) are just getting started adding corals to our tank. Got a Zoa frag last week. It looked great for the first 8 days it was in our tank and then closed up really tight. I noticed a white dot on one of the polyps (the one at the very top of the frag in the middle). Is this Zoa Pox? If not, any idea what else might be wrong or what we should do?
Tank parameters
Amonia: 0
Nitrite: 0
Nitrate: 15 PPM
Phosphate: .25 (just purchased some phosban to get this down but am unsure about making any changes until I know what is going on with Zoa)
PH: 8.1
Salinity: 1.023
KH: 161
Calcium: 420
Lighting: 2 Radion Gen 2's
Tank is 110 Gallons and has been set up for 14 months
Flow: 2 returns from sump/refugium and one internal flow pump. There are high areas of flow and lower areas of flow. The flow around the Zoa's is fairly gentle.
Livestock: 1 Rabbit fish, 1 engineer goby, 3 clowns, 1 pajama Cardinal, 1 coral beauty, and 1 neon basslet, 1 sally lightfoot crab, assorted snails, cleaner shrimp, peppermint shrimp, 2 pistol shrimp, sand sifting starfish, and hermit crabs. There are also a bunch of copepods/amphipods.
