Do you have any other corals in the tank? How do they look? If all is well except the zoanthids, then that link might link it.![]()
What light? what size tank? location of zoas in tank? ,etc...
So its just loosing some of its vibrant coloration?
Are you feeding it any?
Could be too little light.. higher nutrient levels,etc..
A phase perhaps? (morph)
I wouldn't do anything drastic just yet. If everything else is ok just let things play out.
I get a kick out of the Raccoon btw... Such a beautiful friend.![]()
IMO.. The fluval/marinland,etc... lights are just not suitable for corals at all.. No matter what "reef capable" marketing blah blah they put on them..
Thats more than likely the problem.. IMO
For real? I spend some money of this stupid light. Ugh
Sorry....
Its an LED light with only 25W of output.. Its simply not sufficient for 99% of corals..
FWIW.. I run 2 x 120W fixtures (set at about 50%) over my 40G breeder tank
A very ..very general rule for growing any coral under LEDs is
watts = surface area of water in square inches divided by 18 times 3..
So a 36" x 18" tank would need 36x18/18x3=108 Watts
