Greetings all. I normally don't ask for stocking suggestions. I ussualy have a pretty good idea what I want or see something and research it for compatability etc. The situation I have right now is a reefer 170, 34g display. About 40 gal total. I have some large fleshy lps coral and a bunch of stick frags. Current fish are a copperband butterfly and a lawnmower blenny, along with 1 blood red fire shrimp. My nutrients are low. N barely detectable except when dosing sodium nitrate. Phosphate is undetectable but came back as 0.01 on a recent icp test. I want to raise nutrients by adding another fish or 2 so I can feed more as apposed to dosing. I realize at some point the butterfly will have to be moved to my other tank but no plans on that being in the immediate future as it has some growing to do first. Any suggestions? I thought about cardinal fish but I'm really not too fond of them. The CBB is the center piece for now and the blenny stays hidden except when I feed. I guess I could do one or maybe one of each bengi or pj but wanted to seek suggestions first. It's a bare bottom tank so I dont know if there are any small wrasse that may work? I don't want anything even remotely aggressive as the CBB has been a fish I have always wanted and it is doing so good I don't want to take any risks with aggression. Thanks for reading this somewhat long winded post. I added a pic so you can see the rock scape
