Blue Tetra

by Fish Tank on September 8, 2006

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.
