Bumblebee Goby

About

Found in the coastal waterways and estuaries of Malaysia and Indonesia, Brachygobius xanthomelas is one of several small gobies that hobbyists commonly group under the name 'bumblebee goby'. A label that suits them well given the bold yellow and dark brown banding that wraps around their stubby little bodies. Adults top out at under an inch, making them among the smallest fish you can keep in a home aquarium. Like other members of the genus, they use fused pelvic fins as a suction cup to perch on rocks, wood, and substrate rather than hovering in open water, which gives them an endearing, almost frog-like presence in the tank. They do best in brackish conditions that reflect their estuarine origins, so a bit of marine salt in the water goes a long way toward keeping them healthy long-term. They tend to be peaceful toward tankmates their own size but can be territorial with each other, particularly males, so giving them plenty of hiding spots helps reduce friction. Their small size and brackish requirement narrow the list of suitable companions, but within a species-appropriate setup they are manageable even for less experienced keepers willing to do a bit of homework first.
