Though the coloring of the Red-Finned or Leconte's Loach can vary, it is generally brown to yellowish or light blue to light green-blue. It is also darker on top and lighter on the belly. The fins cam be a pale yellow to an orange red and there is a large dark spot at the base of the caudal fin. Juveniles have narrow dark vertical stripes and can be an iridescent green color, but the stripes will disappear as they mature.

Often times mistaken for its close relative the Redtail Botia Botia modesta, the Red-Finned Loach is very similar to it in body shape and coloration. The most distinguishing feature that defines the Red-Finned Loach is the dark spot at the base of the tail when it is an adult. The Redtail Botia differs by having a dark vertical (and often indistinct) stripe, but never a spot.

Though a nocturnal fish, meaning it is active in the evening and during the night, the Red-Finned Loach is peaceful and suitable to keep in a community environment with other peaceful fish. They are rather shy however, and will acclimate to the aquarium best if they have the company of their own species. It is recommended that they be kept in a group of five to eight, with three being the minimum.

The Red-Finned Loach is a durable fish, but it does need soft acidic, slightly warmer water, and must have frequent water changes. The substrate needs to be a fine gravel or sand that does not have sharp edges. Provide lots of hiding and resting places in caves, rocks, and roots. They like a well planted tank but they are diggers and may uproot them.
