If I understand it right, a welso actually looks like a puffy brain so it gets called a brain, but a brain coral is actually in the favia or favites family.
Which one is more desirable? Which one cost more? I know this is a subjective question but I only have enough room for 1 of these guys and need help deciding. What's a fair price for a 4 inch rainbow open brain?
Well. if space is an issue then I'd go with a "brain". They are relatively slow growers. My welso started at about 4" and ended up around 9" across before i had to sell him because he was too big. Aside from that, my personal preference would still be welso. Not all of them are really puffy, I like em puffy.
