Advice on this Tubastrea

[Elo500]

Picked up this sun coral cheap from Lfs because he was having trouble with them. I've been keeping it in the sump because there are a few pods and it's easier to get to when I feed it. I've been putting it in a container a few times a week with frozen cube of mysis. It will start to open a little and I create a flow with a dropper swirling the mysis around and some sticking to the sun coral. Is there anything else I can feed it to help it recover ?

You should have no problem with that one. The heads are still open. Mysis and finely chopped shrimp work great. The very best is live white worms. They stay alive for 24+ hours in salt water and the wiggling of the worm really wakes the Sun coral up. Another option for waking up Sun coral is to gently blow live BBS into the mouths with a pipette.

When we had ours, we fed it Hikari frozen squid. They did very well on that.
