Care Guides

The Penguin Tetra (Thayeria boehlkei) is a hardy and active schooling fish known for its unique angled swimming behavior and bold black stripe. Best kept in groups, it adds movement and personality to community aquariums.

The Sailfin Tetra (Crenuchus spilurus) is a subtle but rewarding species known for its dramatic dorsal fin displays in mature males. Best suited for natural, low-light aquariums, this fish offers unique behavior and a transformation that develops over time.

Collett’s Tetra (Moenkhausia collettii) is an underrated South American tetra that brings natural movement and clean schooling behavior to planted aquariums. Easy to care for and great in groups, it’s a perfect alternative to more common tetra species.
