Often overlooked, black fish for aquariums can make a striking display in any tank. You may choose to only stock black aquarium fish, which can be stunning in densely planted tanks or themed tanks such as avatar designed aquariums. You may also want to consider stocking an aquarium just with black fish and another solid color fish, maybe red or white, making a stunning contrast.
The following black or mostly black colored aquarium fish make great additions to most aquariums.

Probably the most well known black fish, the back molly is a solid black aquarium fish. The black molly is a popular aquarium fish as it has a great personality, deep black colour and is peaceful. These livebearer fish are omnivores who will spend most of their day picking at and grazing algae from the aquarium.
Black mollies make excellent community aquarium fish as they are peaceful and don’t tend to bother other fish. As mentioned, black mollies are omnivores meaning they appreciate a well-balanced diet of plant and meat-based foods. They love live food and the more live food they eat, the deeper their color.
Black Moor Goldfish
I love the black moor goldfish, and it was the very first fish I kept as a young child. Black moors have lovely temperaments and are fun to observe. The unique and quirky eyes and body shape make them fascinating black fish to keep.
These fancy goldfish are almost always a hit with children due in part to their look and the way they swim. However, as with all goldfish, they do require adequate filtration and good water quality.
If you want a cold-water fish, the black moor goldfish is a beautiful fish that is black.
Angelfish are a popular aquarium fish and have been around in the hobby for a long time. Angelfish have many different color variants, including a near back variety. Black angelfish are stunning fish. They look great in black only angelfish groups or when mixed with other contrasting angelfish, such as the Platinum White Pearlscale Angelfish.
Black angelfish make great additions to densely planted aquariums. They look great against green plants but also contrast beautifully against red aquarium plants.
Black Neon Tetra
An often overlooked near blackfish is the black neon tetra. These stunning little fish are black versions of the normal neon tetra. Black neon tetras, like neon tetras, are best kept in groups of at least six as this will keep them happy and feeling safe. The more Black neon tetras, the better though. A large group of black neon tetras is quite something to see in a densely planted aquarium. Black neon tetras make great fish for nano aquariums.
Black Emperor Tetra
The black emperor tetra is a near back fish with beautiful blue eyes. These peaceful omnivores make great additions to community fish tanks. Black emperor tetras are bred in captivity; in fact, they were created by fishkeepers and are not native fish.
Black Knife Fish
The black knife fish makes an interesting talking point when you have visitors! These unusual-looking black aquarium fish have a distinctive knife-like body shape. The black knife fish can grow large, up to 20 inches, and will require a large tank. They are also semi-aggressive and need an intermediate care level to keep them happy and healthy.
Although not a black fish for most aquariums, the black knife fish is certainly a beautiful fish to admire.
Elephant Nosed Fish
The near-black elephant nosed fish is an unusual looking fish. It has a small trunk-like nose, hence its name.
The elephant nosed fish navigates by using a weak electrical field that surrounds its body. It tends to spend most of its time on the bottom of the aquarium searching for food.
The elephant nosed fish is not recommended for beginners as it has demanding care requirements. However, if you have the experience, these black fish make unusual looking pet fish.
Tibee Caridina Shrimp
While not a fish, the tibee caridina shrimp is a stunning near black freshwater shrimp. These beautiful black shrimps look amazing against densely planted green aquascaped aquariums. They spend their day scavenging and keeping the aquarium clean. If you are looking for a black shrimp, the tibee caridina shrimp may be worth considering.
Black Oscar Fish
The near-black oscar fish is a striking oscar fish variation. Some near back oscar fish have small flecks of red colour, making for a very striking contrast. If you are looking for a large, striking fish with lots of personality, you might want to consider the near back oscar fish. It should be noted that oscar fish grow very large, very quickly. They will require large aquariums, lots of filtration and will eat anything they can fit in their mouths.
