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.

Paracanthurus hepatus
The blue tang — Dory from Finding Nemo — is one of the most recognizable marine fish with its vivid royal blue body, black palette marking, and yellow tail. While stunning, they grow large (up to 12 inches), are highly susceptible to ich, and need tanks of 75+ gallons. They are not beginner fish despite their popularity following the movies.
