Azure Damselfish



The Damselfish is also called the Half-blue Damselfish is a darting, two-tone marine fish. The front of its body is blue. The posterior part, the anal fin, and fins are yellow. There is a variation by species with regards to the proportion of the yellow visible on the bodies of fish. (Some people call C. parasema to be the Azure Damselfish, but in the world of aquariums it is known as the Azure Damselfish is thought to be C. hemicyanea.) A 30 gallon tank or more with lots of decor and rockwork is the ideal choice. Because it is tolerant to low water parameters it is a sought-after fish with novice hobbyists. A small amount of Azure Damsels that are young can add flare and color to the majority of marine aquariums. It is important to keep this species alongside other fish that are semi-aggressive, since they may become territorial when they grow older. In larger reef aquariums this should not be an issue if there are plenty of hiding spots available. The Azure Damselfish diet must consist of high-quality flake food as well as frozen meaty items such as brine or mysis shrimpand, occasionally, dried seaweed served via a feeding clip. Approximate Purchase Size: Small: 3/4" to 1-1/4" Medium: 1-1/4" to 2-1/4"; 2-1/4" to 3"

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.
