The Signal Goby: A Master Mimic with a Sketchy Captive Survival Record

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.

The Two-Stripe Damsel: Hardiness and Hostility in Equal Measure

Among the pomacentrids (damsels and clownfishes) are many species that rank exceptionally high when it comes to hardiness in aquaria (thus their once common use as tank cyclers) but also tend to mature into little hellions that can turn a peaceful community tank into an underwater war zone. The genus Dascyllus contains more than its … [Read More]
