The X-Ray Pristella Tetra is an unusual member of the Characidae Family that has a near transparent body. This novel characteristic gives this tetra the appearance of a living x-ray photograph. However, unlike true clear or glass-like fish, the X-Ray Pristella Tetra has a captivating color pattern that adds another dimension of interest. The dorsal and anal fins have stylish bands of yellow, black, and white. In addition to these bands, the caudal fin has a beautiful pale red or pink coloration that offers yet another unexpected surprise to this seemingly transparent fish.

In the wild, the X-Ray Pristella Tetra is found in coastal rivers of South America of varying water chemistry. This natural tolerance to a wide range of water parameters makes the X-Ray Pristella Tetra well suited for the community aquarium. Unlike sensitive tetra species that need to be kept in soft water conditions, the hardy X-Ray Pristella Tetra is an excellent choice for new aquarists. Furthermore, the X-Ray Pristella Tetra is very peaceful and is compatible with other non-aggressive fish.

The ideal aquarium setup for the X-Ray Pristella Tetra will include live plants, rocks and driftwood to recreate natural habitat and provide hiding spaces. The X-Ray Pristella Tetra is a schooling fish and should be ideally kept in groups of six or more. Similar to other tetra species, the male X-Ray Pristella Tetra will tend to be smaller and thinner than the female.

The natural diet of the X-Ray Pristella Tetra consists primarily of small insects and planktonic animals. However, it will accept frozen or freeze-dried brine shrimp, daphnia, bloodworms tubifex, as well as micro pellet food and high quality flake foods.

Customer Testimonials

Victoria K Los Angeles , CA
This is a great fish. I have 2 in my 10 gallon aquarium right now and they stick like glue! They swim around sometimes,but mostly just chill in their favorite spot in the aquarium. They are kept with a hatchetfish, and a chinese algae eater with live plants. They are a fun and unique fish to keep, would recommend giving them a buddy if you purchase one because they are somewhat of a schooling fish.

Purchased 12 of these guys during the lockdown to replace stock that had died off due to old age. All fish arrived alive, healthy, and are doing very well now a month later. Would recommend ordering from Liveaquaria for anything you need!
