General information regarding Harptail Blenny They are excellent for reef tanks and able to take on most aquarium fish foods. The Blenny Family is commonly confused with the Goby family. The Blennies are distinct by their single dorsal fin, and the tendency to rest on the bottom of their tanks with their bodies curved. The majority of these fish have tiny appendages at the upper part of their head, referred to as "cirri". Certain Blennies are found in tidal waters in which the waters are cool and shallow. They possess an amazing leaping ability and can be seen jumping from pool to pool. Additionally, Blennies can be found in caves and crevices on coral reefs. They have heads that are blunt and teeth that are combed, which gives them the ability to scrape algae, their main food source off rocks surface.

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.
