Sun coral is sick

Redbird5 · 2026-08-31T17:20:45-0400

I got a sun coral from QCC about three weeks ago. When i got it, it was doing fine and then last week I noticed that its skin starting to recede.

These pictures are from the last week. It's eating, well polyps are out when I offer food twice a day.

A.I says it looks fine and improving. It's AI I don't know I put a lot of stock into what it says. If I tell it I thibk it looks bad it agrees.

Any help or advice would be appreciated.

Mysis brine 2x a day. Reef Roids once a week and Gonipower once a week and phyto broadcast in the aquarium once a week.

hm, Im not sure. I would keep trying but only foods with higher nutrients, brine shimp is kinda bad.
When I tried keeping these I was dosing multiple species of phyto throughout the day and they still didnt do that great for me

Here's my captive bred sun coral. He's been in the tank longer. He's thriving.
