My main display 210g is species specific. I have a gorg dominated tank. Since these guys do NOT play well with others, I have a couple leathers, sponges, mushrooms and that is it. I am adding non-photosynthetic in the next few months. Getting my phyto and brine in order first.
I can try to get pics, but not easy for me. I am terrible with cameras. :)
My 40gal is LPS dominate (maze brains (platy, gone, etc), favia, favites, lobos too) but houses some sps too
Why? Well, I loved the movement of gorgs. The subtle beauty and textures always got to me. Then when I had a few, they began taking the tank over. As I said, these guys do not play with others, so eventually I had to move all lps to another tank. So, it became species specific. Now, I will be adding some non-photosynthetic gorgs to the mix and maybe a carnation coral if those are successful.
Love my lps specific too.
