Why does my sea fan close up?

[Reeffer]

i've recently bought an orange sea fan, it hasn't opened up for the past few days.

Today the polyps opened up fully but they closed when i turned on the lights.. why issit so?

Try placing it somewhere where the current flows throught it, provide adequate lights and also feed some phyto!

Thanks man. Its opening up again... I think it was probably shocked by the lights suddenly turning on?

btw, can anyone tell me whats the biggest kind of food that they can take?

bbs is too big for them already right?

My gorgonians took cyclopeeze before. BBS should'nt be a problem. The thing is to feed them a variety of foods without compromising your water quality. Feed phytoplankton, rotifers (frozen will work too) and selcon if you could. If its orange it might be photosynthetic as I have kept those with orange polyps before. You will have to provided sufficient current like RAV-65 said so that any mucus produced can be swept off easily. Periodic stirring of sand to create a suspension of micro-organisms will make your seafan happy too. Don't stir too deep if you have a deep sand bed.
