Green sinulara and Xenia help.

[Primetime62]

Good day! New here to the page, I recently add a green sinulara frag along with some pumping Xenias on Saturday as well as a diamond goby to my 20 gal tall tank. Both looked good that day and Xenia were pumping good! Then next morning they have both been shrunkin in and Xenia look super deflated.. My tank was setup May 15. I use RO water and Reef Crystals salt mix. Running 30 watt. aqua night LED light. Any advise? I know the crab isn’t helping! Parameters are
Sal. 1.027
temp 78-79
PH 8.1-8.2
Ammonia 0
Nitrite 0
Nitrate 5.0 ppm
Cal 400-420
Alk 10-11 dkh
Phos. Less than .25 ppm

How is the flow on them? These guys like a good amount of current.
It’s not uncommon for soft corals to close up for seemingly no reason. They are quite temperamental, so I’d give it a few days before getting super worried.

I've mentioned this elsewhere, but xenias can literally grow in a toilet - so I think they'll be fine. You may want to augment your flow with a small wavemaker though.

Thanks for the reply, I am using a Hygger mini wave maker along with the return from my HOB for flow.. Should I up the Annie and add another?

To my knowledge that should be okay, maybe just try to angle it so the corals get a bit more flow.
Welcome to the forum btw!

Thanks! I’ve been away from the tanks for a while but have been in the hobby for 20 years! Way back when T5 lights were new! Most my tanks were 55 gallons with sumps. I know bigger tanks allow more room for error. Had to add this guy, just because I’m working from home today.
