Taking the top spot in this week’s AquaNerd Picture of the Week is a cute little fish with tons of personality, a Caribbean Masked Goby (Coryphopterus personatus), seen here hanging out amongst the soft corals of a nano aquarium. These tiny gobies stay under an inch in length, for the most part, essentially making them perfect candidates for all those desktop nano and pico aquariums that adorn our kitchen counters and desks at work. Like most gobies, the masked goby is relatively easy to care for and quite hardy. These tiny fish will eat virtually anything you throw at them, and their demeanor is such that they will get along with just about every other species you put in the aquarium. They will, however, quickly become lost in a large reef aquarium and could potentially become food for larger fish…especially hawkfish, lionfish, groupers, and even some other fish that you might not normally consider to be predators.
Hat tip to Steve Bitter for helping us ID this gorgeous little fish.
