Care Level: Easy

Tiny native livebearer with subtle tan coloration and dark lateral stripe. Peaceful nano fish that thrives in groups and adds gentle movement; appearance varies slightly by individual.

Flakes, micro-pellets, frozen foods

Best Buddies: Works well with peaceful community fish such as small tetras, livebearers, and corydoras. Avoid long-finned tankmates, as males can occasionally nip during breeding displays.
