Anomalochromis thomasi – A Comprehensive Guide (Butterfly Cichlid)
The Butterfly Cichlid, Anomalochromis thomasi, is one of the most peaceful cichlids you can keep—full stop.
If your experience with cichlids is:
- aggression
- territorial chaos
- fish flipping your aquascape overnight
…this one is going to feel like a completely different category.
Visually, they’ve got:
- Soft gold to tan body tones
- Iridescent blue/green speckling
- A distinct dark mid-body blotch
- Subtle red/orange edging in the fins
They’re not loud—but they’re detailed. And once they settle in, they’re a really nice mix of color, pattern, and personality.
Origin & Habitat
This species comes from West Africa, including Sierra Leone, Liberia, and Guinea.
In the wild, they’re found in:
- Slow-moving streams
- Shallow river margins
- Heavily vegetated areas
Typical conditions:
- Warm water
- Soft to moderately soft parameters
- Leaf litter and submerged structure
Very calm, sheltered environments—not high-flow river systems.
Size
- Adult Size: ~3 to 4 inches
- Body Type: Compact, laterally compressed
They’re small enough for community tanks, but still have enough presence to stand out.
Tank Size
- Minimum Tank Size: 20 gallons
- Recommended: 29+ gallons
They do best in:
- Pairs
- Small groups in larger tanks
More space = less stress and more natural behavior.
Water Parameters
- Temperature: 75–82°F
- pH: 6.0–7.5
- Hardness: Soft to moderately hard
They’re adaptable and forgiving, which makes them a great entry point into cichlids.
Temperament
- Peaceful
- Mildly territorial when breeding
- Generally community-safe
This is one of the rare cichlids where:
You don’t have to build the tank around aggression
Important notes
- Very shy with aggressive tank mates
- Best with calm, non-nippy species

Tank Setup
They really shine in natural setups.
Ideal setup
- Sand or fine substrate
- Plants
- Driftwood
- Moderate lighting
Why this matters
They prefer:
- Cover
- Structure
- Calm environments
Too open = shy behavior
Too aggressive tank mates = hiding fish
Diet
Very easy to feed.
Staple foods
- Quality flakes
- Pellets
For best condition
- Frozen foods (bloodworms, brine shrimp)
- Occasional live foods
They’re not picky and usually eat readily.
Tank Mates
This is where they really stand out.
Good tank mates
- Tetras
- Rasboras
- Corydoras
- Small peaceful cichlids
- Livebearers
Avoid
- Aggressive cichlids
- Fin-nippers
- Very large or boisterous fish
They do best in calm, balanced community tanks.
Behavior
- Mid to lower water column
- Calm, deliberate movement
- Interactive without being aggressive
They’ll:
- Explore slowly
- Interact with their environment
- Display subtle social behavior
They’re not flashy in movement—but they’re engaging over time.
Breeding
This is where they really shine.
Spawning basics
- Substrate spawners
- Eggs laid on flat surfaces
- Strong biparental care
Both parents:
- Guard eggs
- Protect fry
- Move fry as needed
They’re actually excellent parents and one of the easier cichlids to breed.
Why They’re Underrated
A few reasons:
1. Not flashy enough at first glance
They don’t grab attention in store tanks.
2. Misunderstood as “just another cichlid”
People expect aggression and skip them.
3. Compete with more colorful species
They get overshadowed by brighter fish.
Final Thoughts
If you want:
- A peaceful cichlid
- Something community-friendly
