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 ?
