Is this a "Brain Coral"?

[bk6662]

I haven't been able to positively ID it with others I've seen yet. If it is, I'm told they have "Long Sweeper Tentacles" that are usually extended at night. So far I haven't seen it look any different than it looks in this picture (haven't seen any tentacles extended). Should I keep looking? I'd like to feed "him" when they do extend. Otherwise does it look healthy to you guys?

Thanks!

It does look like some sort of brain to me (there are a zillion kinds). Look for feeding tentacles after lights out - it may not put them out all the time. You may be able to get a feeding response by using a baster to baste some mysis or something similar over the brain

Looks like a lobo brain to me...give it a few days to adjust, and you'll start to see the tentacles come out at night.

1+ Looks very much like a Lobo. They are sensitive to abnormal alk and they like low to moderate light.
