Species Profiles
Congo Tetra
Phenacogrammus interruptus
Congo tetras are the showstoppers of the tetra family. Males develop spectacular flowing fins with an iridescent rainbow sheen that shifts from blue to gold to green under aquarium lighting. They are larger than most tetras (up to 3.5 inches) and need a spacious, well-planted tank to display their full beauty. Peaceful but shy — they thrive with calm tank mates.

Pearl gouramis are widely considered the most beautiful gourami species, with a body covered in iridescent pearl-like spots over a brown-silver base. Males develop a stunning red-orange chest and throat during breeding displays. They are one of the most peaceful gouramis, making them excellent centerpiece fish for community tanks.
