Blennies for Saltwater Aquariums
Blennies are peaceful toward other species, but can be highly territorial toward their own kind. A blenny will do best in an aquarium with live rock and a good couple of inches of sand bed on the bottom of the tank. These small fish will spend much of their time perched on rocks in the aquarium or on the bottom of the tank. Saltwater fish such as these are the reason many freshwater aquarium owners decide to take on the challenge of setting up a saltwater aquarium for the first time. With patience and care, a blenny can make the challenge worthwhile.
