My first SPS corals. Two look very happy...one has no polyp extension

[Subliminal]

Hey ya'll. I recently picked up a few frags from local reefers, and had a question.

If you look at the picture below, you can see the green slimer has polyp extension for days. It stays like that 24/7. The green goblin in the background also looks happy, with its polyps out. The blue acro, however, has not shown a polyp. Given, the latter two have only been in the tank for ~30 hrs...but I'm wondering if this is normal, or a potential issue?

Thanks!

These look ok to me. Unfortunately your tank is too new for SPS I am afraid these frags will go downhill over time.

Some sps won't show much polyp extension during the day. Check at night with a flash light.

I'll see what's up this evening.

I think you'll be fine. I've always dosed Acro power daily

Just check and monitor your levels
