Looking to add a new fish and wanted to see if anyone could give me a recommendation. I've got a 29 gallon, 30" tank. 1 ocellaris, 1 tailspot blenny, and 1 royal gramma. I was thinking of a pink streak wrasse but they're proving to be tough to find. I'm not really a fan of cardinalfish or chromis. Tried a sixline and that didn't work out.
