Yellow Bumble Bee Cats - Microglanis Poecilus | Live Freshwater Fish

Natural habitat

Yellow Bumble Bee Cats (Microglanis poecilus) are native to Colombia, South America. In their natural streams and microhabitats, they explore rocky crevices, plant roots, and soft substrate along the bottom, bringing subtle motion to a peaceful community aquarium. Their distinctive yellow-tinged markings help them stand out against greens, browns, and substrates, adding visual interest as they quietly patrol their microhabitat.

Adult size

These small catfish remain compact in captivity, typically staying in the miniature to modest size range. Individual growth can vary with tank conditions and available food, but they are consistently among the smaller members of bottom-dwelling catfish in community tanks.

Temperament

Peaceful and curious, Yellow Bumble Bee Cats are well suited to calm, mixed-species communities. They stay close to the substrate, skimming and exploring rockwork, roots, and hiding spots, without displaying aggression toward tankmates.

Tank size

Best kept in a peaceful community setup with ample bottom space. A minimum of 20 gallons is recommended for a small group, with larger tanks providing more hiding places and reducing any potential social stress. Prioritize a setup that mimics their natural microhabitat with soft substrates, plants, and crevices.

Diet

Omnivorous and adaptable, they readily accept sinking pellets, frozen foods, and live foods. Offering a varied diet supports coloration, activity, and long-term health. Feed in small, regular portions to ensure all bottom-dwelling residents have access to nourishment.

Compatibility

Pair these catfish with small, non-aggressive tankmates in a calm community tank. Avoid larger, boisterous species that may outcompete them for food or overwhelm their bottom-dwelling lifestyle.

Care level

Accessible to hobbyists with basic aquarium maintenance. A routine of regular water checks, gradual changes, and stable parameters keeps Yellow Bumble Bee Cats healthy and engaging over time. Their calm demeanor makes them a reliable and rewarding addition for evolving community aquariums.

Water parameters

Maintain stable water conditions with gentle filtration and consistent water chemistry. Aim for a calm tropical environment with minimal fluctuations in temperature, pH, and hardness. Consistent maintenance and gradual adjustments help support their bottom-dwelling behavior and overall wellbeing.

Breeding notes

Breeding information for Microglanis poecilus is not detailed in this listing. In home aquaria, maintaining optimal conditions for breeding can be challenging and typically requires specialized setups beyond standard community tanks.

Quarantine and after-purchase care

All fish are quarantined and observed for a minimum of 7 days before entering our main system. We still recommend quarantine after purchase to ensure acclimation goes smoothly and to protect your new Yellow Bumble Bee Cats and existing tank inhabitants.
