The large colony of my blue zoanthids appear to have some white spots that I think could be Zoa Pox.
None of the other zoanthids are showing these symptoms. Also, the smaller frags of the same colony in my 50gal frag tank are not showing these symptoms.
Other than having the white spots, the coral appears to behave normally and opens completely when the lights are on.
This colony has been in my tank for about 6 weeks.
Here are the water parameters as of yesterday's test:
Ammonia/Nitrite/Nitrate : 0
Specific Gravity: 1.025
pH: 8.0
Calcium: 450ppm
Alkalinity: 8.7 dKH
Mg: 1440
Temperature: 79F
This section of the aquarium is under a 120W LED fixture, Blues are set to 100% while the 20,000K whites are set to about 40%.
Could it be too much light for the blue zoas? My other zoanthids and palythoas seem to like that light combination.
My blue zoa frags in the frag tank are under 4x65W PC lights, and are about 6 inches below the water surface.
I have read that people have had successful results with using Furan-2 to treat Zoa Pox, but some people also said that the zoanthids will recover naturally as long as the water parameters are good.
Has anyone encountered or treated zoa pox before?
I am not sure what could have triggered this. I have not made any significant changes to the tank recently.
The only thing I could think of is that winter time kicked in big time and outside temperatures have dipped (Day, Low 50s / Nights Low 30s). But those are outdoor temperatures and the tank temperature stays stable around 79F.
