The marine aquarium hobby is second only to the US military when it comes to the number of acronyms its members throw around. (Quite fittingly, this past Monday was the 27th anniversary of my DOE.…
The signal goby (Signigobius biocellatus), aka the twin-spot, two-spot, or crab-eye goby, is an appealing little sand sifter with fascinating behavior that, unfortunately, often adapts very poorly to aquarium life.…
