I have noticed that my sun corals are quick to open as soon as the pumps are turned off for feeding time. Is this a Pavlovian reaction, or are they better placed in zero current?
do they open before you feed when the pumps are off or during the feeding process? not to sure but i know that when i turn my pumps off my fish dart to the surface but i wasnt to sure that sun coral had the same feelings. maybe someone else can chime in
Mine starts to open at the same time every night, right before feeding time, while the pumps are still on. I was told by the staff at Preuss that it would learn my feeding schedule and start opening then or just before.

Sun corals, also known as Tubastrea, are beautiful and fascinating corals often chosen by reef aquarium enthusiasts. Proper placement is crucial for their health and the health of your overall reef ecosystem. Here are some tips:
Low Light and Low Flow: Sun corals are non-photosynthetic, which means they do not rely on symbiotic algae for nutrition. Instead, they feed on plankton and small organisms. Therefore, they don't need intense lighting. In fact, they prefer low to moderate light levels. Similarly, they don't do well in high flow areas, as it can inhibit their feeding.
Secure Placement: Sun corals should be placed on a stable surface, such as live rock or a coral mount. Make sure they are securely attached, as they can detach and fall if not properly anchored.
Feeding Accessibility: Since sun corals are nocturnal feeders, they should be placed in an area where they can extend their polyps freely without being disturbed during the night. This means avoiding areas with heavy traffic or aggressive tank mates that might nip at their polyps.
Distance from Other Corals: Sun corals have sweeper tentacles that they use to catch food. These tentacles can sting nearby corals, so it's important to place them with enough distance from other corals to prevent any damage.
Water Quality: Ensure good water quality parameters, including stable temperature, pH, and salinity. Regular water changes and monitoring are essential for the health of all corals, including sun corals. FMWhatsApp
Observation: Keep a close eye on your sun corals after placement. Watch for signs of stress or aggression from other tank inhabitants. Adjust their placement if necessary to ensure their well-being.
By following these guidelines, you can provide an optimal environment for your sun corals to thrive in your reef aquarium.
Sun corals (Tubastraea spp.) extend their polyps during low-current periods, preferring low-flow environments; adjust their placement and feeding to mimic their natural habitat for better health.
This colony opens ~ the same time each night, but ALWAYS seems to be triggered by the water movement stopping... feeding only begins when the water movement has stopped. I have noticed too that they are open AT night, or rather - early in the morning, when the tank is still dark, and the morning sun hasn't reached them yet...
