Hi, there is a reef tank at the location I'm working for that the people there would like to change the stocking of. The coral is all soft or anemones and the fish are currently a Black Sailfin Blenny, a Sailfin Tang, and a Sixline Wrasse. There's also a Creole Anthias that most likely won't be staying much longer cause it's too much of a bully. The tank is 100+ gallons, I'd reckon about 180 though it could be smaller. The location wants to have some clownfish and a blue tang, although I will probably try to talk them out of the latter. They also seem interested in a pistol shrimp-goby pair. What are some interesting stocking options that you would recommend (preferably ones that are comfortable or intriguing to children?)
