Identification Tips

1. 1

   Body Pattern

   Look for the distinctive, irregular vertical dark bands on a lighter brown or yellowish background. These bands are typically numerous and can be branched or Y-shaped.

2. 2

   Barbels

   Observe the four pairs of sensory barbels around the mouth, which are characteristic of loaches and used for detecting food in the substrate.

3. 3

   Suborbital Spine

   Note the presence of a sharp, retractable spine beneath each eye. This is a key defensive feature of Botia species, though it may not always be visible.

4. 4

   Size

   Adult Zebra Loaches typically reach a maximum standard length of 8-10 cm (3-4 inches).
