Three Spot Domino Damselfish Info The Domino Damselfish is an attractive and sturdy display fish for your aquarium particularly when they are in schools. But these adorable fish rapidly transform into monsters that pursue and harass fish that are much larger than they are. They make great partners for marine fishes who are aggressive, such as other damselfish, dottybacks, puffers, and angelfish. Give plenty of swimming and hiding areas for them. They should not be used in reef aquariums in which they are in close proximity to peaceful coral inhabitants.   Three Spot Domino Damselfish Diet Damselfish are tolerant of any kind of marine-based diet that you can offer them. Feed them a diverse diet that includes frozen mysis shrimp, fresh shrimp silversides, flake pellet, and various commercially prepared food items. Provide enriched food items to prevent them from becoming faded.

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.
