Species Profiles
Axolotl
Ambystoma mexicanum
Axolotls are fully aquatic salamanders native to Mexico City's Lake Xochimilco. Critically endangered in the wild, they thrive in captivity and have become incredibly popular pets. Known for their permanent larval form, external gills, and remarkable regeneration ability, axolotls require cool water and specific care that differs from typical fish keeping.

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.
