subject: Tropical Fish Information [print this page] When setting up a beginner fish tank one of the most exciting steps is choosing which of the many species of fish to keep. The Pristella maxillaris, or more commonly known as the golden pristella tetra or x-ray tetra fish, makes a great choice. Also known as the goldfinch tetra and the rarely used signal tetra, these adaptable fish will not only entertain you and keep you company but their see-through appearance will also liven up any dull conversation.
These fish get their multiple names because of their intriguing appearance. Not only are they fairly transparent, they feature colorful top and bottom fins of yellow and black. They have an iridescent body color that is accentuated by their transparent backend.
Hailing from coastal rivers in Brazil, Guiana, Guyana, and Venezuela, the x-ray tetra is adaptable to many types of aquatic habitats. They can tolerate pH levels of 6-8 and hardness up to 20 dGH. This flexibility makes the pristella tetra a popular choice for many when setting up their first tank. That said, they do prefer soft, slightly acidic water and a water temperature between 72-82 degrees Fahrenheit or 22-28 degrees Celsius.
The x-ray tetra fish plays well with others, with the exception of aggressive or predatory tank mates, and like to live in small to large groups. If you are adding these little gems to your community tank be sure to purchase at least six to ten.
There are no strict diet requirements for the golden pristella tetra. They will eat flakes, frozen, freeze-dried, and live foods. They do love delicious flake food as well as bloodworms and brine shrimp so be sure to keep your pets happy and give them a treat now and then!
Another benefit, or downfall depending on your tank, is that the x-ray tetra is a breeding fish. Provided you have two compatible fish in your tank they will spawn eggs that hatch within twenty-four hours. The hatchlings should be feed liquid food for egg laying fish or brine shrimp when they are able to consume them.
