Dojo / weather loach tank mates
A 25 cm temperate loach that acts as a barometric pressure indicator by increased activity before storms. Hardy and peaceful but too large for most tropical setups.
Common mistakeParking a dojo loach in a warm tropical community because the shop tank looked fine is how keepers invent mystery infections. These fish prefer the cool side of the range, often 18–22°C, and sit poorly above the mid-twenties for months on end. Pairing them with discus-temperature stocks burns both plans. Buy length and cooler honesty, not a 24–28°C community sticker.

The Dojo / weather loach profile lists White Cloud Mountain Minnow as a recommended pairing. White Cloud Mountain Minnow schools in groups of 6 or more, so plan room for the whole group rather than one fish. White Cloud Mountain Minnow grows to about 4cm, which is borderline mouth-size for an adult 25cm Dojo / weather loach.
