New to lps, quick question

Hi everyone, I'm just getting into the stony corals. Mainly LPS. I purchased a small frag of trumpet coral with 5 or so heads and I just had a quick question about actinics only.

At night time when my actinics are the only thing on, are the stony corals supposed to close up almost completely to where I can see their skeleton, or is there something wrong? Maybe because I just added it to the tank and it could be stressed? I can see it's small sweeper tentacles out, but I just had to ask.

Thank you.

 

sounds ok to me, especially since its new. Mine still close up a lot at night.

 

Thanks I appreciate the fast response. I'll see how it looks tomorrow.

 

yeah, i have a lot of LPS in my tank and sometimes they close up for 3 days if i look at them wrong.
a pic always helps thug.

 

thug? lol.

and my tank is only a little over a month old, so i was curious.

 

sorry things? autocorrect!lol

A month old is EARLY for coral. Your cycle may not be complete yet. I'd keep up with some water changes until your cycle is stabilized to keep it alive.

 

how long do you recommend i wait before adding more coral? my parameters are all in check.

 

also my trumpet is doing fine.

 

Wait, a month since the cycle ended or a month since you added stuff and started the cycle?

 

well, technically its about 2 1/2 months old. I pretty much let the tank sit for about a month with just saltwater and a piece of live rock from my father's established tank (been up for over 3 years). then i added more live rock and live sand. added the clown and the hermit crabs at about 2 months. and now the coral at about 2 1/2 months. I really started this tank early january, but i just counted it since i started adding more stuff into it.
