Petruichthys sp. 'rosy'

Rosy Loach

This species continues to be referred to by the fictitious scientific name ‘Tuberoschistura arakensis‘ but actually appears to be an undescribed Yunnanilus sp. and is also sometimes traded as Y. sp. ‘orange’ or ‘Burmese pink loach’ but appears to be a member of the genus Petruichthys as per Kottelat (2012).

There exist more than 30 described Yunnanilus spp., the…

In the aquarium they will acc…

It can however be distinguished by the following characters: presence of 8-12 very regular dark bars on flanks (vs. 10-13 irregularly-shaped bars in N. spiniferus), 3-5 times…

N.anguilla can be told apart from other Indian members of the genus by possessing dark flank markings which are partially or completely merged to form a lateral stripe, and an almost-complete lateral line extending to the anal-fin.

Kottelat (2012) states that its generic placement requires additional study hence the genus name i…
