The bumblebee catfish is a name commonly used for several small, striped catfish species. The most popular one in the aquarium trade is the South American bumblebee catfish (Microglanis iheringi), native to South America. Another is the Asian bumblebee catfish (Pseudomystus siamensis), which comes from Southeast Asia. Here’s some information about them:
 
South American Bumblebee Catfish (Microglanis iheringi)
 
    •    Appearance: Black or dark brown body with yellow or cream bands, resembling a bumblebee.
    •    Size: Usually grows to about 2.5–3 inches (6–8 cm).
    •    Habitat: Found in slow-moving freshwater rivers and streams in South America.
    •    Diet: Omnivorous; eats small invertebrates, insects, and detritus. In aquariums, they will accept sinking pellets, live, and frozen foods.
    •    Behaviour: Nocturnal and peaceful, making them good for community tanks with non-aggressive species.
 
Asian Bumblebee Catfish (Pseudomystus siamensis)
 
    •    Appearance: Similar striped pattern but with a slightly different coloration and body shape.
    •    Size: Larger than the South American species, reaching up to 6 inches (15 cm).
    •    Habitat: Prefers streams and rivers in Southeast Asia with good water flow.
    •    Diet: Predatory; feeds on small fish and invertebrates, requiring meaty foods in captivity.
    •    Behaviour: More territorial and best kept with tankmates of similar size or in species-only setups.
 
Aquarium Care
 
    •    Tank size: At least 20 gallons for smaller species; larger for the Asian variety.
    •    Water conditions:
    •    Temperature: 22–27°C (72–81°F).
    •    pH: 6.0–7.5.
    •    Soft to moderately hard water.
    •    Setup: Provide hiding spots like caves, driftwood, and plants for their nocturnal nature.
 
Both species are fascinating for hobbyists due to their striking patterns and unique behaviors.
