speaking of tiny zoas...i've been noticing them on my LR as hitchhikers as well...and most of the times, they have the brightest colors i've ever seen usually including neon green, blue, pink. but literally, they are the sizes of a pinhead.
I was just looking through zoaid to figure out if my bright orange zoas were bambam oranges, the 2 little polyps in the middle of this pic look a lot like the ones I have:
I think thats what they are. Mine came in on a wild colony. I got a tiny rock off it with 3 polyps, all different. lol This was one of them. I lost my original bam bam orange colony to that infection
My bright orange zoas (I suppose I can call them bam-bams now LOL) are the brightest thing in the tank, they are probably the smallest polyped zoas I have but they really are eye-catching. You can see them from across the room!
