    My Sun Coral starts to shown similar symptoms than the Sun Coral of Warr7207 in March.

    Sun Coral Question - General Coral Care

    I have the sun coral in a Boyo tank. I feed it once a week shredded mussel (mix pack from P&P), hake and Cyclopeez? by using the half bottle technique. Although it opens every night I am concern that I am missing something. How can I help it to recover it's former glory, or is it too late?

    :please:

    All the polyps is still allive but it shown decay around the rim area (I appologies for the picture quality):

    Hi Jubs, Sun Corals are not the easiest corals to keep, When you feed them do they keep the food in or do they spit it out after a while? Also what is your Cal reading?

    The food particles are small so I have not notice this behavior. I will definitely take a closer look next time. I am not very familiar with all the "shorthand codes" - will you please elaborate on the Cal values.

    Calcium...................380 to 450 mg/L

    Try and feed them bigger pieces of food it might be that the don't get the required amount. When they open you can feed them 5mm pieces of hake or mussel.

    If I didn't welcome you yet, welcome to MASA Jubs! Hope you like it here :)

    He's talking about calcium. Can you please tell us more about your tank, how long it's been running etc.
    What are your water parameters? Especially nitrates, kH, calcium and salinity.

    Sun corals need to be fed at least every second day - which makes it difficult to keep in a nano as that can have a direct impact on water quality. You need to squirt some food into the tank first, wait for all the pollyps to extend and then place the bottle over it making sure ALL the pollyps get food.

    I think 5mm is too big. I kept a suncoral succesfully on coral frenzy and brine shrimp. Here is pic of how mine looked in my previous tank. I had him for almost a year and he always looked like this :)

    Because of their difficuty to keep many people actually remove it from the tank for feeding. Put in a shalow container with tank water.

    I target feed my Sun Coral from Monday to Sunday with Coral Frenzy (as I do to all my other corals), but on a Sunday I fill a two litre plastic bucket with tank water and place my Sun in the plastic bucket, I then use either frozen mussel pieces or frozen brine shrimp. I stir the water about every 30 minutes for the next 4 hours.
    My Sun was also looking poorly until I started this method about 6 months ago. The Sun has not only recovered but has also started sprouting little polyps at the base of the bigger and older polyps.
    Try it and see.

    So you saying you place the coral in the plastic bottle and leave it in there for 4 hours. Doesn't the temperature change and oxygen levels in the container change. I'm pretty sure I'm missing something.

    I do stir the water every 30 minutes or so - and I have been doing it about six months now and the Sun has improved dramatically so I must be doing something right.

    Thank you all for the excellent information. :thumbup:

    So far:
    1. Check the water quality (Cal & kH - the rest is ok)
    2. Feed more offen (especialy with live baby brine shrimps)
    3. I am planning to replace the Boyo (in a few weeks time) and will definitly incorporate a darker spot in the new design.

    I have had no problems with it stressing - in fact when I take out the bucket the polyps are so swollen with food they look like the points of my thumb.

    I don't know what the difference is between Cyclo-Peeze and Coral Frenzy. The LFS recommended Coral Frenzy and my corals do well on it so I have seen no need to try anything else.

    And I must also add that the polyps come out when the lights are on - I do have it in a position where it only gets indirect light - please see the pics in "Ted's new tank" thread under the large tank portion of Members Systems

    Coral Frenzy is much better than Cyclops-eeze in my opinion. Cyclops-eeze tends to float too much and then go over the overflow, it is also way overpriced against Coral Frenzy. Coral Frenzy stays longer in the water column :)

    Sorry that the pics in the tub are not the best but it does give one an idea on how the sun feeds.

    just careful with this technique in terms of temp of the water and amount of food you put in the bucket. i learn t the hard way and killed a good15 heads. i am now doing damage control to the 4 heads that are left. A little mistake and bamb you got troubles and feel really bad.

    But this is the best technique if you don't want additional problems in your tank because of "OVER FEEDING."

    Still one of the best corals to have i reckon
