So I was thinking about tank mates for my bipolar blenny. I know they're playful fish and like company, so what should I get? I was thinking a clown or hector's goby and a cleaner shrimp or sexy shrimp. The only drawback to the goby is that it also likes rocks to hide in. I don't have too many rocks in my tank, and it's already smaller than I would want a bicolor blenny in, so I don't want to push for space. An open swimmer would be the best choice, but are there any that can live happily in ten gallons? Remember, the fish come first, so I don't want to push it. The only reason I don't think a clown goby is the best idea is because I heard that bicolor blennys become aggressive to similarly colored fish. Maybe I could get a green one?
