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
  • Interesting behavior without aggression

The Butterfly Cichlid is a fantastic choice.

It’s one of those fish that:

Doesn’t demand attention—but earns it over time
