best aquarium fish

Regardless of what aquarium fish you choose for your aquarium tank, there are some aquarium fish that always make the top ten aquarium fish lists. These aquarium fish include angelfish, neon tetras, goldfish, and more. In this article, I would like to talk about aquarium fish. Specifically, the top ten aquarium fish.

I’m sure you have heard of some of these aquarium fish before, but perhaps not all of them. Here are my top 10 aquarium fish that you should consider for your aquarium tank.

10. Silver Arowana

The silver Arowana is an aquarium fish that has the potential to grow up to two feet (24 inches) in length and can live up to 50 years or more. This aquarium fish is also known as the “dragon fish” because of its bulging eyes, sharp teeth, and long tail. The aquarium fish can be quite aggressive in an aquarium tank. If you are looking for aquarium fish that are good jumpers, then this aquarium fish might just fit into your aquarium tank nicely.

9. Red Tailed Catfish

The red-tailed catfish is popular with aquarium lovers because of its bright coloration consisting of a reddish-brown body with white spots outlined in black along its body and fins, including the tail fin. With their large mouths, these aquarium fish can grow up to 30 inches or more in length. However, 30 inches will not happen overnight since it takes time for this aquarium fish to grow. They are carnivorous aquarium fish that enjoy eating aquarium fish such as guppies, aquarium fish fry, aquarium fish smaller than themselves, and even aquatic plants if given the chance. In addition to this, they can be a little aggressive as well as territorial as adults.

8. Blue Zebra Cichlid

The name says it all about these aquarium fish. The aquarium fish is blue with white horizontal stripes or bands running from head to tail on each side of its body. Adults will also have a black spot at the base of their dorsal fin where juveniles may lack a spot entirely until later in life when they begin developing it. With an adult size of up to six inches long, these aquarium fish are great aquarium fish to add to aquarium tanks of small aquarium enthusiasts.

7. Silver Hatchetfish

The silver hatchet fish is a popular aquarium fish and comes in several colors, including pearl and gold. This aquarium fish gets its name due to its large, flat head that gives it the appearance of a miniature hatchet or broadaxe when viewed from the side. This aquarium fish will spend most of its time near the surface looking for food such as fry (babies) of other aquarium fish such as guppies and aquarium fish larvae, insects, crustaceans; they may even eat smaller aquatic plants if given the chance. These aquarium fish can grow up to three inches in length with females growing larger than males on average. They are also aquarium fish that tend to get along fairly well with other aquarium fish.

6. Bala Shark

The aquarium fish is popular with aquarium owners because of its resemblance to saltwater aquarium fish such as the clownfish and the percula aquarium fish due to its orange color. This aquarium fish can grow up to four inches in length when fully grown in an aquarium tank with a 10-gallon capacity or more. If you have a breeding pair, then they will need at least 20 gallons of water for them to breed since these aquarium fish are known for being prolific breeders in captivity if provided the necessary aquarium conditions they need in order to reproduce successfully. In addition, these aquarium fish can also be territorial so avoid keeping two males together in an aquarium tank because they will fight.

5. Blue Gourami

The aquarium fish is known for its beautiful blue color, especially the males of this aquarium fish species that are more vibrant in their color. The aquarium fish can be territorial with other aquarium fish and may nip the fins of other tank mates including smaller aquarium fish such as neon tetra, guppies, and aquarium fish fry so it’s best to keep them alone or with larger aquarium tank mates since they do grow up to five inches long when fully grown. These aquarium fish are also prone to jumping out of an aquarium tank if given the chance so you need to make sure your aquarium has a tight-fitting lid on the top of it since these aquarium fish can jump quite high at times.

4. Harlequin Rasbora

Harlequins are aquarium fish that resemble the neon tetra with their bright red color and black horizontal lines on their body, which is why these aquarium fish are commonly confused with neon tetras in an aquarium tank setting. However, aquarium owners will notice that they don’t have the blue stripe on their dorsal fin as neons do. Also, harlequins grow up to two inches long when fully grown whereas neon reaches only one inch long as adults. As juveniles (when newly born), they can be mistaken for danios since both aquarium fish species possess a similar pattern but harlequins tend to be smaller than danios at this stage of life so it’s an easy way to tell them apart. When fully grown, they will show their true colors and you will be able to see the black horizontal lines running down its body so it’s best to keep aquarium fish species that are similar in size together since these aquarium fish tend to school together when swimming in an aquarium tank.

3. Pearl Gourami

This aquarium fish is one of the most popular aquarium fish because of its bright yellow coloration that stands out well in almost every aquarium tank setting along with being great algae eaters due to their herbivore habit. These aquarium fish can grow up to three inches long when fully grown in an aquarium tank with a capacity of 10 gallons or larger. It is best to keep them alone in an aquarium tank because they tend to be territorial and may fight with other aquarium fish including their own kind if kept in a smaller aquarium tank. In addition, these aquarium fish are known for being excellent jumpers so it’s best to have a lid on your aquarium tank since they can jump up to one foot high from the aquarium floor at times.

2. Dwarf Gourami

The aquarium fish is also known as “honey gourami” or “dwarf honey gourami” due to its orange coloration along with an extended dorsal fin that resembles a coronet crown around its head which gives this aquarium fish its name. They can grow up to two inches long when fully grown so it’s best to keep them in aquarium tanks that provide 10 gallons of aquarium capacity or more. They are very peaceful aquarium fish and can be kept with aquarium fish such as kuhli loaches, rasboras, danios, angelfish, and corydoras without any problems. However, avoid keeping them with neon tetras because they become food for the aquarium fish since they have a similar orange coloration to them so it’s best to keep them in aquarium tanks by themselves or with other aquarium fish species that resemble their body shape and size.

1. Neon Tetra

The aquarium fish is one of the most popular aquarium fishes today due to its bright blue stripe on each side of their body which is how these aquarium fish get their name from (“neon” meaning blue in Greek). They are also very small aquarium fish growing up to only one inch long when fully grown so it’s best to keep them in aquarium tanks that have a capacity of 10 gallons or larger since these aquarium fish tend to school with other aquarium fishes. However, avoid keeping them with harlequins because they have a similar pattern but harlequins do grow up to two inches long when fully grown whereas neons only reach one inch long as adults so there might be size differences between aquarium fish species kept together in an aquarium tank setting.
