General Description
The Metzia Formosae, commonly known as Garras Crossocheilus Tanichthys, is distinct from other species due to its superior mouth and a longitudinal black stripe on its flank extending from the gill opening to the caudal-fin base. This species is part of the Cyprinidae family and reaches a maximum size of 7.5 cm.
Aquarium Setup
The Garras Crossocheilus Tanichthys prefers slow-moving to still habitats with clear to turbid water and abundant aquatic vegetation. Setting up the aquarium to mimic these conditions with appropriate vegetation and ample space for swimming is recommended (see table for more details).
Behaviour
In its natural habitat, this species is commonly found alongside other fish species such as Metzia lineata, Barbodes semifasciolatus, Rasbora steineri, and Macropodus opercularis. It exhibits typical behavior for a cyprinid fish, being relatively peaceful and active.
Feeding and Diet
The Garras Crossocheilus Tanichthys is an omnivorous species, feeding on a variety of foods including algae, small invertebrates, and plant matter. In a home aquarium, they can be fed a varied diet of high-quality flake food, pellets, and occasional live or frozen foods.
Reproduction & Dimorphism
Sexual dimorphism in this species is evident as sexually mature females tend to have a deeper body compared to males. The reproductive behavior of Garras Crossocheilus Tanichthys in an aquarium setting is not extensively documented.
Habitat and Distribution
The Metzia Formosae is primarily found in northern Taiwan, Hainan Island, Hong Kong, southern China (Guangxi and Guangdong provinces), Yunnan province in China, and northern Vietnam. There are also reports suggesting its presence in Laos. The species prefers habitats with slow-moving or still water, often in streams, rice paddies, and canals where aquatic vegetation is abundant.
