Will it open more Large? Sun Coral?

I try the container method, and it doesn;t seem to open that much. I don't know why I'm having such a hard time with this...
 
So you think i should keep trying, everyday at the same time?

What did is i place the coral in the container and place a cube of food in it. It did open but barely in 30minutes.

How long does it take for a sub coral to be fully open during feeding?
 
I don't know, maybe a minute the way I do it. The few that open when I put my hand in the tank do it in about a minute as well.

Did you just drop the cube in, or did you blow it around with a syringe or turkey baster?
 
Sorry, I had to say it. Sun corals are NONphotosynthetic, so they won't care if you've got your tank in a lightless basement all day or with 5 kajillion watts of metal halide lighting. Ok, it might, cause that'd be damned hot and they DO like to open up when it's darker, but the point is the amount of light doesn't matter. They seem to be pretty hardy, and I'd say anyone that really wants to keep sun corals and has the time and energy to devote to feeding them constantly can keep them.
 
Well, depends how much time you feed them. For example you can feed them every 2days, but you will have to feed them more than everyday.

I on the other hand feed it everyday, but I'm having a hard time feeding it. If you have 250w MH's, you might consider placing on the bottom of your tank. Depends how deep your tank is, making sure that it doesn't get to much lighting or the tissues with get damage.
 
2 400s on my suns in a 75, no tissue damage. Nanocubeboy, the polyps come right out whether the light is on or not. Just keep at it. It should work eventually.
 
I have a small colony of sun corals that are not doing well (newbie but learning).....i think i was probably not feeding enough...this post and Melev's info have been very helpful.....I am seeing them respond to the new feeding schedules :) ....thanks!
 
I noticed that they do not like nitrates at all. I had problems keeping them in a 12 gallon nano-cube. I fed them all the time but they receeded. Having them in such a small tank causes water quality to go down because of all the food always present. IMO not good for a small tank but it can definitely be done with a lot of effort. Good luck
 
i have some of mine in a 12 & they're doing great. i take all out to feed in a separate container, though, as not to foul the water.

fishfanv, what steps when you feed your corals in the container?
Click to expand...
i fill a large (i have 5 different suns) container with tank water around 8:30 at night every other day or sometimes twice a week depending upon how tired i am that night. i put some cyclop-eeze in the water to get them to come out if they're not already. then when they're out i target feed each polyp with a mixture of cyclop-eeze, f1 & mysis. then i let them sit there & finish eating for about half an hour or more and then return them to their tanks. i've been using this method for about 6 months or so and all my suns have grown like weeds! i've even seen some tiny little suns on random parts of my live rock (not the rocks the suns rest on).
