Indian Butterfly Gobies are so cool! Also known as Wasp Fish, these guys can sting if being handled. We dont recommend handling any of your fish unless moving them in or out of an aquarium with an net, but be careful when moving these guys. They grow to be about 2.5 inches in an aquarium. These gobys have surprisingly large mouths for their size, so we recommend keeping them with fish their size or slightly larger. Feeding them frozen foods such as bloodworms or brine shrimp will keep them happy. They prefer to be kept in groups of at least 3, so a 20 gallon aquarium or larger is recommended.
