Overview
The Bumblebee Catfish (Microglanis iheringi) is a small, peaceful yellow-and-black banded catfish that hides by day. It is a popular choice among Australian aquarists, reaching around 8 cm and living roughly 4-5 years when properly cared for.
This complete guide covers how to keep the Bumblebee Catfish successfully - tank size and setup, water parameters, the best foods (including recommended brands), suitable tank mates, breeding, sexing and the health issues to watch for. It is rated Beginner to care for.
Natural Habitat & Origin
This catfish comes from the rivers and streams of South America or Africa, foraging along the bottom for food. It appreciates hiding places, soft substrate and clean, well-oxygenated water.
Matching the temperature, water chemistry and cover a species evolved with is the simplest route to keeping it healthy and seeing its natural behaviour and colour.
Tank Size & Aquarium Setup
Provide a minimum of 75 litres for the Bumblebee Catfish. Give it a large footprint with sight-breaks and cover to reduce territorial aggression.
Include driftwood and caves for shelter; wood aids digestion for many plecos and gives bottom-dwellers somewhere to feel safe by day.
Always add fish only to a fully cycled, mature tank with stable biological filtration. Match filtration generously to the fish's size and waste output.
Water Parameters
Keep the Bumblebee Catfish in stable water at 21-26 °C with a pH of 6.5-7.5. It adapts to a moderate range, so stability matters more than an exact figure.
Test regularly: ammonia and nitrite must read zero, and nitrate should be kept low with routine partial water changes. Always dechlorinate and temperature-match new water, because sudden swings cause far more illness than water that is stable but slightly imperfect.
Diet & Feeding
The Bumblebee Catfish is a carnivore and needs a protein-rich, meaty diet.
In Australia, good options include Hikari Carnivore/Massivore pellets, API Carnivore food and Dymax frozen bloodworm, brine shrimp, krill and mussel. Feed small amounts once or twice a day (only what is cleared in a minute or two), vary the diet for the best colour and health, and avoid overfeeding, which is the leading cause of poor water quality.
Temperament & Tank Mates
The Bumblebee Catfish is peaceful and community-friendly. It mixes well with other calm species that share its temperature (21-26 °C) and pH (6.5-7.5) needs, are too large to be eaten and not large enough to eat it.
Breeding
The Bumblebee Catfish is rarely or not bred in the home aquarium; most stock is commercially farmed or wild-collected, and home breeding is considered very difficult.
Even if you are not planning to breed it, recognising this behaviour helps you understand what you are seeing and respond well - for example by adding cover for fry or giving a guarding pair extra space.
How to Tell Males from Females
Females are generally rounder and fuller-bodied; in many Synodontis and similar catfish, visual sexing is difficult outside breeding condition.
Common Health Problems
Scaleless and fine-scaled fish like this react badly to poor water and to copper-based or full-dose medications, so treat at half strength. They are also among the first to show ich. Quarantine new arrivals for 2-4 weeks and watch daily for early signs such as loss of appetite, unusual hiding, clamped fins or laboured breathing - caught early, most issues are very treatable.
Prevention beats cure: keep water pristine, avoid overstocking and overfeeding, quarantine new arrivals, and act at the first sign of trouble.
Is the Bumblebee Catfish Right for You?
The Bumblebee Catfish suits beginners and experienced keepers alike, as long as you can provide at least 75 litres, water at 21-26 °C and pH 6.5-7.5, the right diet and suitable tank mates.
Meet those needs and the Bumblebee Catfish will reward you for around 4-5 years. Use our free aquarium calculators to plan your setup, and explore our other fish, plant and disease guides to build a thriving aquarium.
