Nocturnal Coral

[ThatGuyMike]

other than sun coral. what are some other kind of nocturnal corals?

im sure theres gotta be more than just that. call myself researchin, and for the past 2 days. i cant seem to find any thing other than sun coral which i already know about.

The open brain coral (Trachyphyllia Spp.) is another that extents its tentacles at night and if your lucky you may catch them out in early morning and plate coral (Fungia Spp.) as well do this. However saying that my plate coral has it's tentacles out night and day; always catching the current in search of food.
What is your interest in night active corals??

Many non photosynthetic corals are nocturnal since, in the wild, thats when all the plankton and stuff come out.

Im not too sure but maybe gorgonians?

something differentfor starters, and im pretty nocturnal myself, so why not nocturnal corals.

im posting this at 6am my time just before going to bed. im not new to the board. just dont post often. im in chat most of the time though

Reading through the former postings I am not sure what you mean exactly with nocturnal but Caulastreas are wide open during the day for "sun bathing" and at night the polyps shrink somewhat but extend feeder tentacles to catch food. So, they are active around the clock but catch food only at night.

(Exactly speaking they catch food during the day, too, if they sense food around them. So, you can feed them during the day, too, you only have to wait a few minutes until they will shove their tentacles out. But the normal behaviour is tentacles in while lights on and out while lights off.)

Agree with Dilbert, but it actually extends further than just Caulastrea. Most corals will expand polyps in the the day time when the zooxanthelles are doing what they do i.e photosynthesize and at night when the light is lowest the feeding tentacles come out to pick up little particles in the water current. The brilliant thing about corals is they are 24 hours a day feeding. It may therefore be seen that food stuffs like chromaplex should ideally be put in after lights out. I mention the open brain and plate since you will easily observe their tentacles. The sun coral on the other hand is non photosynthetic so will really only do the latter half of the daily cycle.

There are a number of corals that open and extend thier polyps at night, not during the day. thus the term nocturnal. im rarely home during the day. and im a nite dweller so i would something that is open at nite. i found out a few of them. one is called a chili coral or chili pepper. and there was several kind on sun coraland a few different anemones as well. so i found ont some of what i was asking about.

this thread can be closed.

Rather than just close it, why not wait and see what further info comes out

For example, if you are about at night, why not just have normal corals and have the lights on during the night?

Also, how do you plan to view these corals which come out at night?

hey andy, good to hear from. long time no chat. ill prolly be on line at work saturday, hit me up. next time u see me on.

someone mentined Fungia but there is also Heliofungia. Dendronepthia is nocturnal but really hard to keep unless you have a tank full of plankton.

Night corals can be viewed with a blue light. It makes most of the other corals fluoresce as well

And will also disturb any fish since reef fish are designed to see very well in the blue light (anyone who dives will understand why as the red and yellow end of the spectrum is absorbed very high in the water column).

If you really want to view the nocturnal habits of a tank you should utilise a red light.
