    Cindy, I've just read that the brain should be kept on the sandy substrate but I've always kept mine on a piece of LR about two thirds of the way up. I just put the meat on my finger and gently touched it to it's mouth (I was guessing it was the mouth at that time). In about 5 seconds or so it stayed there and then it slowly began covering over it. BTW thanks for the link, I'll check it in a minute.

    They typically only send out they're feeder tentacles at night. Irritants like too much phyto/ floating detritus or other things that bump into the coral can cause it it never send out feeder tentacles.

    BTW, I not sure now if mine is an open or closed brain? It's shaped like a figure 8.

    Light only gives up to 98% of energy that photosynthetic corals need.  [/quote]

    Sorry Gresham,

    I'm having a brain fade today :)

    Do you mean that the coral is probably catching the other 2% of the food it needs, maybe just occassionally, and that's why Mikes coral has managed to survive for the past 2 years?

    Not trying to be clever here BTW, just interested :)

    Thanks mike! ;D

    Mine had been at least half way up on the rock and when it really started looking bad I put it on the sand after reading similar info. I'm just waiting. It still doesn't look good. I'll try feeding it again tomorrow.

    No, photosynthesis can only provide up to 98% of required energy for a photosynthetic coral. The other 2% comes from captured food, or taken in in other methods besides sunlight. I'll try to find the link to the study I'm quoting, but for now, alls I can say is it was a Aussie doing to study.

    Cindy,

    If as Gresham wrote that the coral gets 98% of it's energy from the light. then maybe you should move it higher in the tank rather than lower :)

    I don't know where to put it any more. On RC they say it needs to be in the sand bed. The previous owner had it in the sand bed and it was fine. My lights should be ok they are only 4 mos old.

    It had taken in the silverside about half way and when I took the bottle off over the top of it (so the fish wouldn't eat it) the whole silverside floated up so he didn't eat any of it. I don't know what his problem is. I have a green open brain and its doing just fine. Hes in the sand and has been all along.

    I hope he doesn't die. :'(
