Elacatinus prochilos-The Broadstripe cleaner goby is rare in the aquarium industry. Similar to the neon cleaner gobies they are a nano species that helps clean pests and parasites off larger fish in aquariums. This very cool behavior is great to watch and when they aren’t cleaning other fish they can be found under overhangs or hanging out on the glass panels. These are great additions to both small and large aquariums and are completely reef safe.
