Okay, why does this brain expand to 4 times it's orginal size at least once a day then return to normal. It's done this for the last 4 months and some days it looks like it could explode!?!?

It's a sign it's happy. Probably eating phytoplankton and other food in the water column. It should grow rapidly.

It's amazing how much they can expand and retract. Mine does the same, needs a pretty big piece of sandbed to be happy!

Well that's good to know, I've never seen them expanded like that in pictures or at the LFS.
