While they can be a little shy, they are great community fish. They will happily coexist with a variety of tankmates.
It’s best to keep them in a reef tank with ample hiding places to help them feel secure. You should also ensure that your tank has a tightly sealed lid. This is because these small fish are prone to jump when stressed or frightened.

The Banggai cardinalfish is a peaceful species adorned with white spots and splayed fins that give them a distinguished look. They are relatively easy to care for, and their size makes them suitable for smaller saltwater aquariums.

Give them a varied diet and plenty of space to swim. Once you do, they’ll quickly become a favorite in your tank.
Blue-Green Chromis (Chromis viridis)
For those looking to create a visually stunning and lively school of fish, the blue-green chromis is an excellent choice. These hardy fish are easy to care for and thrive in groups, helping to bring life and movement to your tank. It’s best to keep them in a group of at least five to mimic their natural shoaling behavior.
Chromis can also be a bit timid, so providing plenty of live rock for cover is important. With their shimmering blue-green coloration, watching them at school is a captivating experience.
Neon Dottyback (Pseudochromis aldabraensis)
Despite their name, neon dottybacks come in a range of colors, including purples and yellows. These colorful fish are a relatively small species, so they’re suitable for smaller tank sizes but can be aggressive. They are a good option if you’re looking for a bit of spunk in your tank.

Blenny (Ecsenius sp.)
Blennies are a diverse group of fish with many species available for the saltwater aquarium. The two-spotted blenny (Ecsenius bicolor) and the lawnmower blenny (Salarias fasciatus) are particularly well-suited for beginners. They are peaceful and easy to care for and will spend their days perched on rockwork, watching the world go by.
Some species are herbivores. This means they will help control algae in your tank. Just ensure that you have enough natural algae growth to sustain them.
Watchman Goby (Cryptocentrus spp.)
Watchman gobies are known for their interesting behavior and their tendency to pair up with pistol shrimp. The goby will act as a lookout for the shrimp, while the shrimp creates and maintains a burrow for them both to share.
This partnership not only provides an engaging dynamic for your aquarium. It also ensures a cleaner, as the shrimp will sift through the sand and keep it aerated.
Keep watchman gobies in pairs with only one as the shrimp partner. This will prevent aggressive behavior between competing shrimp partnerships.
Hawkfish (Cirrhitidae family)
Hawkfish may not possess the vibrant colors of some other fish species, but their unique personalities make them captivating aquatic pets. They are hardy, adaptable, and generally peaceful, so they’re a solid choice for beginners.
With their perching behavior, hawkfish are often mistaken for blennies but have distinct features. This includes a more elongated body and a sharp and pointed dorsal fin. They can be jumpers, so a secure lid is a must for your tank setup.
Valentini Puffer (Canthigaster valentini)
The Valentini puffer is a beautiful and personable fish that can adapt to various tank sizes. They are known for their striking patterns. This includes a yellow and black body with white spots.
A Valentini puffer can be kept with other peaceful species, but they may nip at their fins. They are also known to eat small invertebrates. So it’s best to keep them in a reef tank where there is less temptation.
