    I have a sun coral had it now for about 1.5 weeks.

    The thing does not like the light & opens only after lights out!

    I have read we can get them to feed with lights on! I have been trying.

    I am using frozen food with syringe to target feed

    Pumps off - target feed then wait 15 Min for them to open a little then target feed again

    I take it - it just takes time to get it into opening when the lights are on?

    Thanks
    Mark

    Yes Vatso - these corals come from dark environments in the sea - so, they are not used to light. It does indeed take time for the coral polyps to get used to the bright light.... also perhaps you should place the coral underneath an "overhang" in your tank - that it is not in direct lighting?

    just target feed when lights are off for now,till it gets used to all the bright lighting.

    what sort of lights do you have in the DT?

    I am running 6 T5's 3 white & 3 blue

    No HOB just a small in tank skimmer

    As light go out it starts to open as the rest go to sleep

    How wonderful these things are & how they know the lights are on or off! I can watch them for hours!

    Hi mVatso,

    I actually take my sun coral out of the tank once a week and put it into a 2litre ice cream bucket filled with tank water. I then feed it with the frozen food - brine shrimp, mysis, mussel pieces, etc. I stir the water every 15 minutes and leave the sun coral in the bucket for about 4 hours.
    Before anybody shoots this down - I have been doing this for about 18 months and my sun coral is healthy and growing. It opens up and feeds well. This has al;so led to the sun coral opening when I target feed all my corals with Coral Frenzy every evening - with lights on.

    Vatso, just remember that a suncoral needs daily target feedings to thrive which can lead to very high nutrient levels in your tank. That can cause high nitrates and phosphates which will fuel nuisance algae. Check your parameters regularly and increase water changes, especially in a smallish system.
