Live Rock Hitchhikers: Tunicates (Sea Squirts)
Among the more fascinating creatures that commonly make their way into marine aquariums as stowaways on good-quality live rock are tunicates, or sea squirts. In terms of visual interest, these animals can be quite dazzling, with some exhibiting spectacular coloration…
Don’t Get Burned by Flame Scallops!

Is There a Jellyfish Tank in Your Future?
One of the product lines that really caught my eye at MACNA 2014 were the jellyfish tanks at the Boyd Enterprises booth. Until recently, home aquarists did not have access to jellyfish systems. When I think of jellyfish systems, I…
Does the Emerald Crab Earn Its Algae-Eating, Reef-Safe Reputation?
Among the various and sundry marine life commonly sold to aquarium hobbyists for utilitarian purposes is the emerald crab (Mithraculus sculptus). Oft touted for its propensity to gobble up bubble algae and other irksome algal forms, M. sculptus has become…
