Blue Tetra

To catch this fast-swimming Blue Tetra, Sakichin had to be quick with the camera. This blue fish, the Boehlkea fredcochui, will grow to only about 1.5 to 2 inches long as an adult. This makes it a great fish to keep in a small aquarium.


It's best to use plenty of plants with the Blue Tetra. They're most comfortable knowing there's a place to hide, and seek cover if needed. The color of the Blue Tetra can best be seen against a dark substrate. If you are just planning your aquarium, you'll want to choose plants, background, and gravel that show your fish off best.

Here are a few things to consider when choosing this fish:

  • Tetra are best kept in groups
  • Belongs to the Characidae family
  • Tank conditions most suitable include 73 - 82°F, pH 6.0 - 8.0
  • Maximum size is 2 inches

The Blue Tetra is an omnivore that will be quite happy eating eats fish flakes or blood worms . Soft acidic water is prefered by this tetra, especially when breeding.

Part of the Characidae family, the tetra has a small adipose fin that makes it different from most other fish. It's believed that the fin is much similar to an appendix in a human. The function is not known.

Stocking the Blue Tetra with fish the same size is best. They would do well with Barbs, Angelfish, Loaches, other Tetras, or non-aggressive fish in the community tank.

Chocolate Gourami

Probably not as edible as a chocolate bar, this great freshwater fish picture by KooshKing is an excellent example of the Chocolate Gourami. An omnivore, the Chocolate Gourami is searching for the next taste of brine shrimp, bloodworms, or tubifex worms.


The Chocolate Gourami, unlike some of his fellow Gouramis, takes a little more care to keep happy. Keeping the water quality clear of ammonia, nitrite, and other deadly enemies is important for the health of your fish. Cloudy fish tank water just won't cut it with the Chocolate Gourami. This colorful fish is a little more vulnerable to bacteria and parasites that attack the skin. Still, this Gourami is a peaceful fish that would do well in the right fish tank with an experienced fishkeeper . Some things to consider about the Chocolate Gourami:

  • Minimum tank size: 30 gallons
  • Adults can reach about 2 1/2"
  • Tank conditions most suitable include 75-85°F, pH 6.0-7.0
  • Best kept in pairs with a well planted tank: Java fern or Vallisneria spiralis are two choices that provide cover

The Chocolate Gourami is also a mouthbrooder. A mouthbrooder will hold their offspring in the mouth for extended periods of time. In the case of the Chocolate Gourami, the female may hold eggs in her mouth for two weeks without eating. Breeding is a very delicate process with this fish. Water quality and diet are important.

A rewarding fish to watch and care for, the Chocolate Gourami would do well with other peaceful fish such as Guppies, Danios, or Minnows
