okay, update with some pics.
tried introducing a royal gramma and a clown goby but they were both eaten by the 6 or 7 pistol shrimp that I have found living in the tank.
I really like watching this pistol shrimp community and may just leave as is and add coral.
in any case, this is all about the pics, let me know what you think.
cheers.
