Is this Favia open?

Recently got this little guy. Placed him with the plug on the sandbed to adjust to the tank. Was wondering if he’s opened up? I’m not sure if the circles in the center mean that he’s not closed up.

I can not tell if the coral is extremely stressed, or if it's a feeding response. Really need an image under white lighting. Even an image under day light would help.

Favia do not have moving parts, and only sometimes show feeding tentacles. You can try looking at night for them
Attaching images with just white lighting! With my regular lighting there is red and bluish coloration. Got this guy 2 days ago.

Thank you!

I don't like the way the coral looks at all. Check your water chemistry including SG. If you have strong LED move the coral to an area of less intensity.

Will update once I do this! It’s a 20 gallon nuvo with an AI prime so I’ll move the frag to the side maybe under a more light-diffused area. BRB

Can you also post your parameters? Your substrate looks new and from your other thread you were just wrapping up your hardscape 2 weeks ago. Thats a VERY quick cycle... tank might not be mature enough for coral.

As of yesterday my ammonia is at 0ppm, nitrates at 20ppm, phosphate at 0.3ppm, 1.025 salinity and alkalinity around 8.3; using instant ocean salt.
I need to calibrate my refractometer to double check the salinity, i’ll try to do that soon.

I used an entire bottle of fritzyme 900 to cycle the tank, about a week later i tested and figured I was cycled, I also have a seachem ammonia alert badge inside that’s reading 0 ammonia.

Thanks all!

FWIW, I have a xenia, gsp, and zoa frags that I added at the same time. I know they are a bit harder to kill than a favia perhaps, but no sign of alarm on them from what i can tell.

Gotcha, next question would be how did you acclimate.
Although you are cycled, your tank/parameters may still not be mature enough or stable enough for corals to thrive. We're a slow and steady bunch here in terms of highest chance of success.

I think the acclimation process probably stressed the little guy out. The temperature took a bit too long to equalize so they were sitting in the container for a long time, perhaps close to 45min-1hr but the temperature struggled to get up there because of the cold room. I added him when the temp got 2 degrees from the DT; i feared that taking too long would be detrimental but if I should keep waiting in the future lmk!
Also… i’m a bit clumsy and while sticking my hand down there to place the frag it did fall upside down and get a lil bit of sand on the coral, which i placed near some flow to get off.

Calibrated refractometer using Randy’s DIY solution, DT seems to be at 1.023. Should i let the tank naturally rise in salinity through evaporation?

user error, salinity seems to be fine now. 1.025

A bit stumped, but I guess I'll give it a few more days and see what changes. I have benereef coming in tomorrow, I'll see if the corals have any feeding response.

it looks stressed. Feeding response would be more inflated.

Also, your coral isn't a Favia; it's likely a Favites or a Paragoniastrea (russelli).
Ah, had my doubts about it not being a favia. Doesn't really look like any favia i've seen online so far, stressed or otherwise. I don't know coral biology lingo, but favias look more...3D? lol
I hope the care for whatever I have isn't too complex though. So you recommend against feeding them at this stage (or trying)? Thanks a bunch
