open Brain coral

That's an awfully high price IMO, is it an unusual colour? I bought my brain from a tank full of 2" x 4" peanut-shaped little brains with two mouths each, they were priced from $69-$89CD depending on colouration. Mine was $10 because it's 90% bleached, but it's starting to take food again and will likely recover. I wouldn't spend that much unless you KNOW it's super healthy, eating well, and it's a little unusual.

theres only so much room so cherry pick the things that go in it... if you like it then buy it.
