Species Profiles
Firemouth Cichlid
Thorichthys meeki
Firemouth cichlids are one of the most beginner-friendly Central American cichlids. Named for their striking red/orange coloration on the throat and belly, they are less aggressive than most cichlids of their size. When threatened, they flare their gill covers to display their bright red throat — a bluffing display that is far more bark than bite.

Danio margaritatus
Celestial pearl danios (also called galaxy rasboras) are tiny, jewel-like fish discovered in Myanmar in 2006. Their dark blue body is covered in iridescent pearl-white spots, with bright orange-red fins striped with black. Despite their exotic appearance, they are hardy and easy to care for — one of the hobby's best-kept secrets for nano tanks.
