Rick Herring's Sunflower Coral
Contrary to popular belief, a vast majority of corals are not autotrophic, requiring only light to survive. Autotrophs produce their own food from inorganic material they extract from their surrounding environment, usually using sunlight to synthesize it with the aid of zooxanthellae algae. Giving your corals some extra food can really perk them up and increase their reproduction rate.

Hi Weng,

I’m assuming when you say “just set up” that it is still going through the cycling process. You didn’t give much info about your tank, gallon size, lighting, living inhabitants or quality of your water. Do you have any cleaning crew? I think that your tank is exactly where it should be and in a few weeks you will see the coralline that has turned white will grow its color back. Don’t do ANY water changes or substrate clean ups while your tank is still cycling. A good cycle will probably be at around 3 months. Hope this helps some.

Hello, we have a 70 gallon bow front saltwater tank that has been set up for about 2 months. The water has cycled and it has been doing just great. We have a variety of nice and very large corals, bubble corals, sunflower, button… and they have all been very happy. There is only 2 damsels, 2 small clowns & 1 small yellow tang. Last week is when we added the tang and the two clowns. Then 2 days later – the corals are white and look wilted. I think they are all dead, but the fish are fine. We have been feeding the corals and like I said everything has been doing so well for the last month & 1/2. Do you have any ideas on what could have happened? Could the corals be recovered?
Any information you could give me would be great.
Thanks.
Michele

One thing I was having trouble with was corals, especially zoanthids not opening. I added some Coral Amino along with Vitamin C and the corals are huge and fully open. One thing I think it needs to be said for any newbee is to take it slow. You need to resist buying too much too fast, if you want a healthy, happy aquarium and its inhabitants.
