Chitala chitala (Bengali: চিতল, Assamese: চিতল "sitol", Tamil: அம்பட்டன்வாளை, சொட்டைவாளை or அம்புட்டன் வாழ) is a knifefish from Bangladesh, India, Nepal and Pakistan,[1] where found in the Indus, Ganges-Brahmaputra and Mahanadi River basins.[2] It is sometimes known as the Indian featherback.[3] In the past it frequently included several related Chitala species, but these are now regarded as separate species.[2][4] The main species confused with this species is C. ornata (clown featherback or clown knifefish); a Southeast Asian species seen regularly in the aquarium trade.[3] The true C. chitala is very rare in the aquarium trade.[3]

Description[edit]

Chitala chitala in Assam, India. Notice the stripes to the back and the dark spots on the lower rear part of the body (both relatively indistinct)

Chitala chitala reaches a maximum length of 122 cm (48 in), but more commonly reaches about 75 cm (30 in).[2] It is overall silvery in color. Unlike all its relatives, it usually (but not always) has a series of golden or silvery bars along the back, resulting in a faint striped appearance.[3][4] Additionally, it has a series of fairly small, sometimes indistinct, non-ocellated dark spots towards the far rear of the body (at the "tail"). This separates it from C. ornata, which has ocellated spots (dark spots surrounded by a paler ring) and lacks bars along the back. The two species have frequently been confused.[2][3][4]
