Twin-Spot Goby

Care Summary

The Twin-Spot Goby is one of the most visually unusual fish in the hobby, waving those eyespot-adorned fins like a tiny aggressive crab whenever it perceives a threat. The mimic behavior is a real antipredator adaptation and watching it perform the display is one of the most entertaining things you can observe in a small reef tank. Keep it as a mated pair because single specimens stop eating without the social stimulus of a partner and slowly decline. It needs live microfauna in the sand and is genuinely difficult to wean onto prepared foods; a refugium-fed system gives it the best chance.
