Aquariums have always been a part of my house. It has become a kind of a family tradition to keep and maintain a beautiful aquarium. My grandmother was the one who was crazy about fish, and I suppose she passed on a little craziness about fish to her daughters. They too have aquariums at their homes, and they passed on the gene of 'fish craze' over to us third generation kids. We cannot imagine our houses without our fish tank, irrespective of whether we have the smallest size or the largest. But, having one was absolutely compulsorily. I enjoy watching my fish swim around the aquarium. My hungry goldfish always asking for food or my majestic Siamese fighter which displays finery in great grandeur. There are many aquarium fish species like salt water and freshwater fish. Many of these types of fish for an aquarium have found a dwelling at our homes.

Types of Fish for an Aquarium

Before bringing home an aquarium fish, there are many things you need to consider about the behavior of the fish. You may bring home fish based on their color and shape, but do you know that many fish types are not compatible with each other and have been found to be aggressive instead. Therefore, you need to consider bringing home fish that are peaceful, friendly, and create a happy environment within the aquarium. There are 3 types of fish for an aquarium, namely, community fish, semi-aggressive fish, and non-community fish.

Community Aquarium Fish

Community fish are the best types of fish that can be brought home by a first time fish owner. These are peaceful fish and have no problems sharing the fish tank with other types of aquarium fish species. These are shoaling fish and enjoy being with many other fish of their own type. The most common community fish that are kept by beginners include:

  • Molly
  • Platy
  • Guppy
  • Neon Tetra
  • Banjo Catsifh
  • Barbs
  • Bronze Corydoras
  • Blue Eyed Plecostomos
  • Lemon Tetra
  • Harlequin Rasbora
  • Honey Gourami
  • Leopard Corycat
  • Swordtail
  • Leopard Danio
  • Masked Cory
  • X-ray Tetra
  • Zebra Loach

These are just a few names of community fish. You have a choice of hundreds of types of these fish species. These types of fish co-exist peacefully in the tank and exhibit a beautiful display of colors and shapes.

Semi-aggressive Aquarium Fish

Semi-aggressive aquarium fish are a little naughty ones. They can live in a community tank but end up nibbing and troubling the little and calmer fish. The Red-tailed Shark and Rainbow Shark are the types of aquarium fish species that can live in a community tank with only the members of their own kind. Tiger barbs can survive with other fish but are semi-aggressive. They tend to have a little fin nipping crave that becomes bothersome for other fish. The following types of fish species are semi-aggressive:

  • Angelfish
  • Black Acara
  • Aurora Cichlid
  • Blue Gourmani
  • Dragon Fish
  • Fire Eel
  • Spotted Puffer
  • Red-Tailed Black Shark

  • Black Ghost Knifefish
  • Three Spot Gourami
  • Krib
  • Electric Yellow Cichlid

If you get any of these fish along with your cool and peaceful community fish, you will surely see some action in your fish tank.

Non-community Aquarium Fish

These fish need a supply of live fish in their diet, and other fish swimming in the same tank become a live prey! Put in a few goldfish and neon tetras with your Tiger Oscars and within 15 minutes you will only find the Tiger Oscars swimming around with a satisfied look. These fish also tend to grow quite large and obviously feed on the little ones. The other types of aquarium fish species that fall in the non-community group are:

  • Asian Arowana
  • Auratus Cichlid
  • Graceful catfish
  • Spoyyed Pirhana
  • Indian Algae Eater

Native to east Asia, goldfish is probably one of the first fish known to be domesticated in garden ponds and fish tanks for recreation purposes. Till today, it is the most sought-after aquarium fish.

Given below is a list of different goldfish types, which you can consider keeping in garden ponds and aquariums.

Common Goldfish: The common goldfish lacks fancy features and is more or less similar to the wild carp, from which the common type is bred commercially. Unlike the ancestral carp, it is found in white, yellow, golden orange, and red. Most of the other fancy types of goldfish are bred from common goldfish.

Black Moor: As the name signifies, black moor goldfish is blackish in color. In recent times, more black moor varieties with variant colors (white, red, calico, bronze, lavender, chocolate) have been developed. Some of them have prominent eyes that protrude out from the head. Such black moor goldfish are also referred to as telescope goldfish.

Bubble Eye Goldfish: A small fancy variety of goldfish, the bubble eye possesses an unusual pair of eyes that point upwards. These eyes are surrounded by fluid filled sacs that resemble bubbles. The sacs, when punctured regrow with time. In aquariums, they should be kept with mild temperament fish.

Comet Goldfish: With a long and deeply forked tail, the comet goldfish is the most frequently kept aquarium fish in the United States. The body shape of comet is similar to the common variety, except that the former is smaller in size and slimmer. Comet goldfish comes in white, yellow, orange, red, and red mixed with white color.

Fantail Goldfish: Fantail goldfish is the oldest breed found in shades of orange and red, which is still reared as pets. It has a very long quadruple caudal fin that accounts to about 33 percent of the total body length. The ryukin goldfish is bred from fantail type.

The fleshy head growth completely encloses the head, except the mouth and eyes. Oranda is available in shades of white, silver, orange, red, red mixed with white or black, bronze, chocolate, blue, and black.

Pearlscale Goldfish: Characterized by presence of thick and dome-shaped scales (like pearls), pearlscale goldfish body is very short, egg-shaped, and resembles a golf ball. It comes in a wide range of colors. Its fins are identical with fantail variety. Any variant of pearlscale having a head growth is known as crown pearlscale.

Pompom Goldfish: You can easily identify pompom (or pompon) goldfish from the two loose fleshy outgrowths located on each side of the head (in between the nostrils). Based on the particular breed, a pompom may or may not have dorsal fins. It also comes in color combination of white, silver, orange, red, and black colors.

Easy to care and graceful with long fins and tail, there is hardly any other freshwater fish that is as variable as goldfish. Apart from aquariums and garden ponds, introducing different types of goldfish to stagnant water bodies help control mosquito breeding. Though it is fascinating to watch

pet goldfish in bowls, never keep them in such a confined space. Rather, you can let your pet enjoy a spacious environment in aquariums or ponds. With correct goldfish care tips and attention, you can enjoy watching this golden beauty for as long as 10 years.

Fish belongs to vertebrate group of organisms living in water bodies, either fresh or marine water. As of date, more than 25,000 fish species are identified and scientists are of the opinion that there are 15,000 more species, which are yet to be identified. The characteristic features of fish are breathing through gills, and presence of paired and unpaired fins that help them in efficient swimming. Besides fins, the body of fish is covered with some sort of protective scales.

Most of the fish species are cold-blooded (or ectothermic) and depend on their surrounding environment to maintain their body temperature. Irrespective of the water chemistry, nearly all water bodies are inhabited by fish. For example, you can find various types of fish in the ocean at such a depth where there is very less or no light penetration. Likewise, several fish species are found dwelling in the streams of high mountains. As far as importance of fish is concerned, they are eaten as food and also, reared as pets in fish tanks.

Fish is an important source of food for humans. Enriched with healthy proteins, they are a delicacy for people who eat animal based foods (non-vegetarians). And for aquarists, fish are wonderful pets kept in decorative aquariums. Indeed, rearing them is a relaxing hobby, which you get to enjoy watching colorful fish swimming, playing, and feeding. Since the demand of fish is very high, fish farming and fishing are sources of income for several people. Mentioned below are lists of edible fish and aquarium fish types.
