Species Profiles
Angelfish
Pterophyllum scalare
Freshwater angelfish are elegant, tall-bodied cichlids that are a centerpiece in many community aquariums. They come in many color varieties including silver, marble, koi, and black. While generally peaceful, they become territorial when breeding and will eat small fish like neon tetras.

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.
