Zoa advice (i think mine are unhappy?)

shootingstar_reef · Mar 13, 2021

hey everyone,

take a look at my hulk zoas. I bought them several months ago, and they were generally doing well. Then they started to slowly open up less and less - you can see in the photo they only partially opened. Since I bought them, I have bought macroalgae and a euphyllia. A month ago, I had to put my fish in quarantine for ich. At first I thought maybe they weren't getting enough light, so I put them closer to the surface, but that has not changed anything. I am unsure how to check what the problem is.

I suppose there might be two things bothering them: a tiny tiny starfish that sometimes roams on the plug, and/or vermitid snails...?

parameters:
SAL: 1.026/34
NH4: <0.02
NO3: <0.5
PO4: <0.04
ALK: 7-8

They don’t look that bad I have noticed my zoas like more nutrients they seem happy when they are higher. You could rent a par meter to see exactly how much light they are getting. It could be something bothering them have you tried dipping them? I would inspect while dipping they are pretty hardy dipping would be fine.

okay that's good to know! I wonder if that's what happened to my sympodium too '-_- I think it needed more nutrients, but that's hard to provide when the fish are in qt haha

Ghost feed the tank with the dust off of frozen food. I drain the crap that comes out of my mysis cubes into a seperate cup from the actual mysis and feed my Zoa with it.
