About Bumblebee Cichlid
The Bumblebee Cichlid (Pseudotropheus crabro), also known as the Hornet Cichlid or Chameleon Cichlid, is one of the most fascinating mbuna from Lake Malawi — and one of the most challenging to keep. It earns every one of its common names: the bold yellow-and-black barred pattern resembles a bumblebee, the aggressive temperament matches a hornet, and its ability to rapidly shift between dramatically different color patterns rivals any chameleon.
What sets the Bumblebee Cichlid apart from other mbuna is its extraordinary wild behavior. In Lake Malawi, it has evolved a unique symbiotic relationship with the Kampango catfish (Bagrus meridionalis), one of the lake's largest predatory fish. Bumblebee Cichlids live in and around the catfish's cave, cleaning parasites from its body — mimicking the pale color of the catfish to avoid being eaten. But the relationship has a dark side: the cichlids also eat the catfish's eggs when it's not looking, switching to their dark color phase to sneak in undetected. This dual strategy of mutualism and parasitism is virtually unique in freshwater fish.
In the aquarium, Bumblebee Cichlids are large for mbuna, reaching 15 cm (6 inches), and highly aggressive. They need substantial tank space and should only be kept with other robust mbuna or large Malawi cichlids. Their rapid color changes — from bright yellow bars to nearly solid dark brown in seconds — make them one of the most visually dynamic fish you can keep.
Natural Habitat & Origin
Bumblebee Cichlids are endemic to Lake Malawi, where they occupy a wider range of habitats than most mbuna. While they're found in the typical rocky littoral zone, they're also commonly encountered over sandy and sediment-rich areas — particularly near the caves of large Kampango catfish (Bagrus meridionalis). This habitat flexibility reflects their unique ecological niche as both algae grazer and catfish symbiont.
In the wild, they're found at depths from 5 to 20+ meters, slightly deeper than many other mbuna species. The deeper rocky zones have less algae but more caves — ideal for the catfish association. The water in Lake Malawi is warm, alkaline, and extremely stable, with minimal seasonal variation in temperature or chemistry.
Their cave-dwelling tendency means they need significant rockwork in captivity, but their willingness to swim in open water differentiates them from more strictly rock-bound mbuna.
Native Region
Lake Malawi, East Africa — widespread across rocky and sediment-rich zones (Malawi, Mozambique, Tanzania)
Habitat Type
Rocky zones and cave environments, often near large catfish; 5-20m depth
Wild Water Conditions
Warm (75-82°F), hard (10-20 dGH), alkaline (pH 7.8-8.6), extremely stable year-round
Appearance & Varieties
The Bumblebee Cichlid's most remarkable feature is its ability to rapidly change color — a trait that earned it the name 'Chameleon Cichlid.' This isn't the slow color development seen in most cichlids; Bumblebees can shift between completely different patterns in seconds.
The primary color phase is the classic 'bumblebee' pattern: a bright yellow to golden body with 6-8 bold, dark brown to black vertical bars. The bars extend onto the fins, creating a striking striped appearance. This is the dominant display coloration, used in territorial disputes and courtship.
The secondary phase is dramatically different: the entire body darkens to deep brown, chocolate, or nearly black, with the bars becoming almost invisible. In the wild, this dark phase is used when raiding Kampango catfish nests — it provides camouflage in cave environments. In aquariums, you'll see this color when the fish is stressed, submissive, or sneaking around the tank.
Males tend to be larger and more intensely colored than females, though both sexes can display full color changes. Adult males can reach 15 cm (6 inches), making the Bumblebee one of the larger mbuna species.

Tank Setup & Requirements
Quick Requirements Summary
Tank Size
Minimum Tank Size
75 gallons
Recommended Tank Size
100 gallons
Bumblebee Cichlids need a larger setup than most mbuna due to their size and aggression. A 75-gallon tank is the minimum for a single male with females; 100+ gallons is strongly recommended for a mixed mbuna community.
Water Parameters
pH 7.5-8.8, Temperature 24-28°C (75-82°F), Hardness 10-20 dGH. Standard Lake Malawi parameters. Buffer with aragonite or crushed coral if your water is soft. Stability matters more than hitting exact numbers — avoid parameter swings.
Substrate
Sand or fine gravel. Aragonite sand is ideal — it buffers pH while allowing natural digging behavior. Bumblebees will rearrange substrate around their territories, especially when breeding.
Plants & Decorations
Extensive rockwork is critical — even more than typical mbuna setups because of their larger size. Build tall, complex rock structures with many caves and swim-throughs using limestone, lace rock, or similar Malawi-safe stone. Every fish needs multiple escape routes. Larger caves are important since these are big fish. Plants will likely be destroyed.
Filtration & Water Flow
Powerful filtration with 8-10x turnover per hour. A canister filter or sump is recommended. Overstocked mbuna tanks generate heavy bioload. Good surface agitation ensures oxygen levels stay high.
Lighting
Moderate lighting that promotes some algae growth on rocks. This gives them natural grazing opportunities and reduces food-related aggression. Standard LED lighting on an 8-10 hour photoperiod works well.
Diet & Feeding Guide
Diet Type
omnivore
Feeding Frequency
2-3 times daily in small amounts
Portion Size
What can be consumed in 30-60 seconds per feeding
Unlike most mbuna which are strict herbivores, Bumblebee Cichlids are true omnivores. In the wild, they eat algae, aufwuchs (the biofilm on rocks), parasites from Kampango catfish, and catfish eggs — a diverse diet that reflects their unusual ecological niche. In captivity, this omnivorous nature makes them slightly easier to feed than strict herbivores, but bloat risk still exists.
Best Foods for Bumblebee Cichlid
- Spirulina flakes/pellets — Should form the base of the diet — 60-70% of all food offered
- Quality cichlid pellets — New Life Spectrum or similar; provides protein without bloat risk
- Blanched vegetables — Zucchini, cucumber, spinach — mimics natural aufwuchs grazing
- Frozen brine shrimp — Good occasional protein source, 1-2 times per week
- Frozen mysis shrimp — Higher protein treat, once weekly maximum
Foods to Avoid
- Bloodworms — High fat content causes Malawi bloat — the #1 killer of mbuna in captivity
- Tubifex worms — Disease risk and high protein/fat — triggers digestive issues
- Beef heart — Mammalian protein is difficult for cichlids to digest, leading to intestinal problems
- Heavy meat-based foods — Even omnivorous mbuna need a primarily plant-based diet to avoid bloat
Despite being omnivores, the bulk of their diet should still be plant-based. Think of them as herbivores that can handle occasional protein — not carnivores. Malawi bloat is always a risk with any mbuna that gets too much protein or fat.
Behavior & Temperament
Bumblebee Cichlids are among the most aggressive mbuna — their larger size amplifies the typical mbuna territorial behavior to a level that surprises even experienced cichlid keepers. Males establish large territories and defend them relentlessly against all comers, regardless of species.
The color-changing behavior is fascinating to observe in captivity. Dominant males displaying the bright yellow-barred pattern will shift to dark coloration when sneaking into another fish's territory or when temporarily subdued by a rival. You'll also see rapid color shifts during feeding frenzies, territorial disputes, and breeding activity.
Conspecific aggression (same-species aggression) is extreme. Never keep two males together unless the tank is very large (125+ gallons) with extensive visual barriers. The dominant male will pursue and attack the subordinate relentlessly. Keep 1 male with 4-5+ females to distribute aggression.
Despite their aggression, Bumblebees are intelligent, aware fish that recognize their keeper and develop distinct personalities. They'll learn feeding schedules and come to the front of the tank when you approach.
Tank Mates: Compatibility Guide
Compatible Tank Mates
Different color reduces aggression; ensure enough rockwork for both
Hardy enough to hold its own; different coloration helps
Keep Demasoni in large groups (12+) to dilute bumblebee aggression
Both highly aggressive — only in very large, heavily rocked tanks
Bottom-dwelling catfish that stays out of mbuna territorial zones
Tough enough for mbuna community; different color avoids targeting
Tank Mates to Avoid
Betta
Completely different water requirements and temperament — would be killed immediately
Neon Tetra
Tiny, soft-water fish — prey item, not a tankmate
Guppy
Would be killed within minutes; wrong water parameters entirely
Angelfish
Too slow and delicate for mbuna aggression; different water needs
Discus
Opposite water requirements, fragile temperament — worst possible pairing
Honey Gourami
Peaceful soft-water species that would be terrorized and killed
Common Pairing Questions
Can Bumblebee Cichlids live with Peacock Cichlids?
Generally not recommended. Bumblebees are significantly more aggressive than most peacocks and will bully them. If attempted, use a very large tank (125+) with heavy rockwork and choose the most robust peacock species.
How many Bumblebee Cichlids should I keep?
Keep 1 male with 4-5+ females. Never keep two males unless the tank is 125+ gallons with extensive visual barriers. In smaller groups, the male will over-pursue individual females.
Can I keep a single Bumblebee Cichlid?
It's possible but not ideal — a single specimen in a community of other mbuna can work if the tank is large enough and other species are equally robust. A lone Bumblebee in a community tank will likely terrorize everything.
Bumblebee Cichlids are maternal mouthbrooders, following the standard mbuna reproductive strategy. The male establishes a territory — typically near a flat rock or in a cave — and displays his brightest yellow-barred coloration to attract females.
Spawning follows the typical egg-spot method: the female deposits a few eggs, picks them up in her mouth, then mouths at the egg-spots on the male's anal fin, receiving sperm to fertilize the eggs in her mouth. This cycle repeats until 20-60 eggs are held.
The female incubates eggs for approximately 21-28 days, during which she doesn't eat. Fry are released as fully formed miniatures at about 10-12mm. In a community mbuna tank, some fry will survive among the rocks if there's sufficient cover. For higher survival rates, strip the female at 18-20 days and raise fry separately.
Fry grow relatively quickly and begin showing barred patterning early. Raise on crushed spirulina flakes and baby brine shrimp.
Health Issues & Disease Prevention
Bumblebee Cichlids are generally hardy when water conditions are maintained, but like all mbuna, they're susceptible to Malawi bloat — a potentially fatal condition triggered by poor diet, stress, or poor water quality. Their omnivorous nature actually makes them slightly less prone to bloat than strict herbivores, but it's still the primary health concern.
Common Diseases
| Disease | Symptoms | Treatment |
|---|---|---|
| Malawi Bloat | Swollen abdomen, loss of appetite, white stringy feces, lethargy, rapid breathing. | Immediately improve water quality, stop all protein-rich foods, treat with metronidazole. Often fatal if caught late — prevention through proper diet is critical. |
| Ich (White Spot) | White salt-like spots on body and fins, flashing against rocks, clamped fins. | Raise temperature to 28-30°C gradually and treat with ich medication. Malawi cichlids tolerate heat treatment well. |
| Aggression injuries | Torn fins, missing scales, jaw damage, hiding and not eating. | Remove injured fish to a hospital tank. Clean water promotes healing. Rearrange rockwork before reintroduction to reset territories. |
Signs of a Healthy Bumblebee Cichlid
- Bright yellow-and-black barring in dominant fish
- Active territorial patrolling
- Rapid color changes in response to stimuli
- Aggressive feeding response
- Clear eyes and intact fins
- Regular digging and territory maintenance
Prevention Tips
- Feed primarily plant-based diet — spirulina should be the staple food
- Maintain excellent water quality with weekly 30-40% water changes
- Keep proper male-to-female ratios (1:4-5)
- Provide extensive rockwork for territory establishment and escape routes
- Avoid overly protein-rich or fatty foods like bloodworms
Frequently Asked Questions
This is completely normal — it's their most distinctive feature. Bumblebees rapidly shift between their bright yellow-barred pattern and a dark brown/black phase depending on mood, social status, and situation. Dominant territorial males display the brightest bars; stressed, sneaking, or subordinate fish go dark. You'll see shifts during feeding, territorial disputes, and breeding.
No. Their large size (6 inches), extreme aggression, and need for a carefully managed mbuna community make them unsuitable for beginners. Start with hardier, less aggressive mbuna like Yellow Labs, then work up to species like the Bumblebee once you understand mbuna dynamics.
They reach about 15 cm (6 inches) in aquariums, making them one of the larger mbuna species. This size contributes to their dominance — they can physically overpower most other mbuna. Plan for at least a 75-gallon tank, preferably 100+.
In Lake Malawi, Bumblebees live near Kampango catfish (Bagrus meridionalis) caves. They clean parasites from the catfish — turning pale to match its coloring and avoid being eaten. But they also sneak in dark-colored to eat the catfish's eggs. This mutualism/parasitism dual strategy is unique among freshwater fish.
Only in very large tanks (125+ gallons) with extensive rockwork creating completely separate territories with no line of sight between them. In most home aquariums, a single male with 4-5 females is the safest approach.
Tips for Keeping Bumblebee Cichlid
Pro Tips
- ✓Watch the color changes — they tell you everything about the fish's mood and social status in real time.
- ✓Add Bumblebees last to the tank — their size advantage over established fish makes introduction easier when territories are already claimed.
- ✓Keep the feeding schedule consistent — hungry mbuna are more aggressive, and Bumblebees are already aggressive enough.
- ✓If you see a female holding (swollen jaw, not eating), she's carrying eggs — decide early whether to strip or let her release naturally.
Common Mistakes to Avoid
- ✗Underestimating their adult size — 6 inches is large for mbuna and they need tank space to match.
- ✗Keeping two males in tanks under 125 gallons — the dominant male will eventually kill the subordinate.
- ✗Feeding too much protein — despite being omnivores, their diet should still be primarily plant-based.
- ✗Not enough rockwork — they need more caves and visual barriers than smaller mbuna species.
- ✗Mixing with peaceful community fish — they will kill tetras, gouramis, and other soft-water species.
