Goby
Yellow Clown Goby
Gobiodon okinawae
A thumbnail-sized, banana-yellow goby that spends its life perched in the branches of SPS coral, watching the tank with big expressive eyes. It is peaceful, nano-friendly, and utterly harmless to inverts, with one caveat for SPS keepers: it will nip Acropora polyps and a female may lay eggs on a branch, causing minor localised recession — a caution, never a blanket reef-no. Keep one unless the tank has several coral heads to spread out territory.
Keep just one per tank — two will fight.
