Zoa Polyps Not Fully Extended

[aidensav]

This tank has just finished the cycle and has had yellow brick road zoa for about a week. Is it getting too much flow?

Personally I think its fine, it looks fine. I think the algae is bothering it not the flow. I would dip that frag in a mix of tank water and peroxide, it will kill the algae very quickly, the zoa will be happier for it. IMO

Is it just those zoas? Might just be the hair algae annoying them. Could dip that plug in h2o2

80% tank water and 20% peroxide for 3-4 minutes and put back in the tank. The algae will die off and your zoe's will be happy. Make sure you have some N03 of around 10 and P04 around .1 to keep them that way.

I’d gently scrub the plug with a medium tooth brush and get some more snails if needed. Zoas are annoyed by the algae touching then.
