Overview
The Polka Dot Loach (Botia kubotai) is a botiid loach from Myanmar marked with a network of pale spots and bands on a dark body. It is a peaceful, active and gregarious species that forms complex social hierarchies and performs the playful 'loachy dance' and 'shadowing' typical of the group, along with audible clicking sounds.
Taxonomy
- Family: Botiidae
- Genus: Botia
- Scientific name: Botia kubotai
Habitat
The species is endemic to the headwaters of the Salween River basin on the Myanmar-Thailand border, including the Ataran and associated rivers. It lives in forest-shaded, well-oxygenated headwaters with clear water, a mixed sand and rock substrate, submerged driftwood and leaf litter.
Tank requirements
- Minimum tank volume: 200 L
- Temperature: 24-28 °C (75-82 °F)
- pH: 6.5-7.5
- GH: 5-12 °dGH
- Group size: 5 or more individuals (10+ preferred)
- Lifespan: 8-12 years
Diet
It is primarily carnivorous. The species takes quality dried products plus live and frozen bloodworm, Tubifex and Artemia, along with fresh vegetables such as cucumber and blanched spinach. It will also eat aquatic snails.
Compatibility
Not especially aggressive, but its activity can intimidate much smaller fishes. It should be kept in a group of at least five or six, and preferably ten or more, to settle its hierarchy. Slow-moving, long-finned species are best avoided as tankmates.
Polka Dot Loach (Botia kubotai) Breeding Guide
Overview
The polka dot loach, Botia kubotai, is a striking yellow-and-dark patterned botiid from Myanmar. Like the majority of botiid loaches it is essentially not bred in the home aquarium, and the fish offered in the trade are produced by other means.
Sexing
Seriously Fish notes that mature females are fuller-bodied with a rounded snout, while males have an elongated snout with noticeably thicker, fleshier lips. These differences are only apparent in mature specimens.
Spawning Behavior & Trigger
No deliberate captive spawning protocol is documented for this species. The single recorded fry appeared spontaneously within a well-stocked community tank rather than from a planned breeding setup, so no reliable trigger or behaviour sequence can be described from the source.
Common Challenges
Successful home breeding is virtually non-existent. Wild-caught and hormone-bred fish are the primary sources for the hobby. The appearance of hormone-induced hybrids on the market is also a concern, as such fish can be mis-sold as pure B. kubotai.
