The firemouth cichlid (Thorichthys meeki) is a species of cichlid fish native to Central America. They occur in rivers of the Yucatan Peninsula, Mexico south through Belize and into northern Guatemala.

Their natural habitat is typically shallow, slow-moving, often turbid, water with a pH of 6.5 - 8.0. It has also been reported to live in cave systems. As fish with a tropical distribution, firemouth cichlids live in warm water with a temperature range of 23–30 °C (75–86 °F). The common name, firemouth, is derived from the bright orange-red colouration on the underside of the jaw. Males in particular flare out their gills, exposing their red throats, in a threat display designed to ward off male rivals from their territory. Source: Wikipedia

Water throughout the T. meeki range is rather alkaline with a moderate hardness, normally over 8 GH with a pH over 7.5. Some lagoons near the sea have a slight saline content. I was surprised however when I saw a few individuals in an apparently hyper-saline spring in the upper part of the Yucatan Peninsula, at Celestum, together with fish well know to have strong saline resistance.

Water temperature is variable within the approximate range 22 to 30°C, having the warmer range at the late part of the dry season from December to May. Rains bring a decrease in temperature in the T. meeki range. Source: The CichlidRoom Companion.
