The body of the fish is predominantly blue, with the black stripe that starts at the chin, and continues across the eyes and then along the dorsal fin. It is most likely to thrive in aquariums if it is provided with live rock in a 10 gallon or greater aquarium. Live rock offers spots to hunt and eat small crustaceans, as well as areas to conceal. It's not typically aggressive unless tankmates have the same shape as it does. The fangs of the White Blenny Smith are for biting an aggressive fish.   The Smith's Blenny diet is comprised of chopped crustaceans and vitamin-rich brine shrimp and frozen food preparations designed for herbivores.   Approximate Purchase Size: Small: 3/4" to 1-1/4"; Medium: 1-1/4" to 2"; Large: 2" to 3"

Smith's Blenny Description The Smith's Blenny or White Blenny has a long, slender, white body that has a lateral black stripe that is across the dorsal fin and runs through the eyes. It is best suited to smaller aquariums. Make sure you have a stable system, with plenty of live rocks for eating and shelter. It's very tranquil, however, when it is threatened, it has sharp fangs that are venomous to defend itself and give a brutal bite. Limit one to the tank. Do not keep fish that resemble the shape of this fish.   Smith's Blenny Diet Blennies consume a wide variety of things, including the vegetable matter that is a source of marine algae.

Helpful Questions From Clients
Frequently Asked Questions
Is hiring a professional necessary to set up a saltwater aquarium?

As a general rule, a larger custom aquarium might require installation by a professional. However, a kit from our online fish store is relatively affordable and beginner friendly. That means you should have no problem setting it up yourself.

Which saltwater aquarium fish should you choose when starting out?

Consider a yellow tang fish. This popular saltwater aquarium fish does a great job of coexisting with other types of fish you’ll find in our online fish store.

How does a saltwater aquarium differ from a freshwater one?

Saltwater aquariums require a bit more maintenance and monitoring than freshwater tanks. Different fish require different levels of salinity, pH tolerances, and temperature requirements. They also require specialized pumps, filters, and other equipment that can handle salt. We can guide you through everything you need to know to set up a healthy, thriving reef tank.

Do fish in a saltwater aquarium swim in a school?

That depends on the species. However, if it’s a fish that swims in a school in the wild, they’ll do the same in an aquarium. Some fish that swim in schools include the green and blue chromis, cardinalfish, and dartfish, for example. When ordering from an online fish store, make sure you do your research on how specific fish species behave to ensure they’ll school (or at least coexist) with your current fish.

Is the effort required to maintain a saltwater aquarium worth it?

Yes! Many aquarists dream of owning thriving saltwater aquariums. You have a tiny piece of the ocean in your home, featuring magical and exotic fish that can only survive in saltwater.
