Green Clown Goby

Gobiodon histrio

The emerald-green sibling of the yellow clown goby — same tiny size, same coral-perching habit, same charm. It nestles among the branches of SPS colonies and is peaceful and invert-safe, but carries the same SPS caveat: it may nip Acropora polyps and spawn on the branches, so pair it with established colonies that shrug off the attention. An excellent, hardy nano fish once it is eating.
