Ok guys been bouncing the thought around for a while now and would like some input. Originally I was plugging all these systems into one and not adding anymore fish to keep the Bioload at a bare minimum but I've decided that I wouldn't mind one maybe two fish per frag tank. I was thinking another rainfords goby cause I love the one I already have but wouldn't kind hearing some other ideas. I'm wanting something that'll stay small, preferably something that grazes, and obviously colorful. Also needless to say it MUST be completely reef safe lol.
