    Thailand, India

General Body Form:

    Underside and back are slightly convex. Small outward facing mouth with 3 pairs of barbels. Although a Botia, sids do have small scales which are not present on the head. Subocular spines are present. Can reach 5 inches (30cm) in length.


    The back is light brownish to light yellow with longitudinal bands that are connected by smaller bands across the back. In young specimens the pattern forms a chain. Underside is white with a silvery sheen. Fins are clear.


    Ideally, botia sidthimunki should be kept in soft water with sand or small gravel substrate. Rocks and roots arranged in the aquarium to provide hiding places are needed to make the species feel safe. Active by day and night. Should be kept in small shoals, 3 being the minimum, 5 or more ideal to bring out their natural behavior. Very active fish that will provide many hours of entertainment. Will accept flake foods but live or frozen foods are more readily accepted.


    Clear, flowing waters of Thailand and India.


    Unknown. Breeding behavior in captivity has been observed but there are no exact details other than they have been bred in the home aquaria. Captive breeding has been achieved, as this species was once thought extinct.

Very entertaining fish, continuously playing at all tank levels, but can be aggressive to certain species especially in the upper tank regions. I have 3 and the largest forced the removal of a betta with his constant fin-nibbling despite being no more than 2.5cm long. Will eat just about anything and is quite useful at cleaning plants and ornaments.
