Hello. I would like help in selecting a fish for my tank. It is a 38 gallon that is mainly zoas and palys, with a few mushrooms. The tank has about 55 lbs of live rock, a hob reef octopus bh-1000, and a couple of powerheads for flow. Lighting is led, started with marineland double bright and added stunner strips etc to get the lighting to where I like it. There is approx 45 watts worth of leds over this tank. Currently in the tank is an ocellaris clown, 2 pepperment shrimp, a couple clams and a few snails, and several frags/colonies of z & p's and mushrooms. The next fish I'm planning on is a royal gramma. After this, I'd like something with a lot of blue, blue like the blue damsels (but don't want a damsel). I'm wanting a peaceful tank, with these three fish and maybe a goby or blenny later. Does anyone have any suggestions? Thanks.
