Beautiful looking corals. For the question on the shirt last I knew they will still available for ordering, can find the information under the announcement forum, might want to check with rev to make sure their are shirts left still.
Here is the link for the shirts https://www.reef2reef.com/forums/announcements/86896-order-your-aquarist-what-we-do.html
Thanks for checking out the coral. And thanks for the heads up on the shirts. Must have one.
