Type of open brain ??

[c0mf0rt]

I got a few "open brains" a few weeks ago and two of them look like figure eights and one has more of a four corner style... the thing is I've only seen feeding tentacles on the four corner one... any ideas on what I might have ??

Pics help out alot more. If you check at night with a flashlight, all the brains should have their sweepers out.
