Protruding telescope eyes that give them a dragon-like appearance
Egg-shaped body different from common goldfish

This unusual combination of traits makes the Black Moor one of the most sought-after fancy goldfish varieties for enthusiasts worldwide.

The Fascinating History of Black Moor Goldfish
Ancient Origins
Long before becoming aquarium favorites, Black Moors have a rich history:
Descended from the common carp, originally drab olive-colored fish
Selectively bred from Prussian carp (Carassius gibelio) or Crucian Carp (Carassius carassius)
Chinese breeders began selective breeding before 1000 AD
Introduced to Japan in the 1500s where breeders developed the distinctive long fins
Originally called “Dragon Fish” or “Dragon Eyes” due to their protruding eyes

Black Moor Varieties and Color Development
How Black Moors Change as They Grow
One fascinating aspect of Black Moors is their transformation as they mature:
Age

Eyes
Color
Under 1 month
Standard egg shape
Normal, not protruding
Brownish-bronze
1-2 months
Developing roundness
Slightly protruding
Darkening to black

Deep velvety black

Many first-time owners don’t realize that young Black Moors don’t display their characteristic features immediately. Patience is key as your fish develops its striking appearance over time.

Popular Black Moor Varieties
Beyond the standard Black Moor, selective breeding has created several variations:
Black Moor with fantail (traditional variety)
Black Moor with butterfly tail (wider, more flowing fins)
Black Moor with ribbon tail (extremely long, flowing fins)
Other black varieties developed from the original Black Moor: Black Oranda Goldfish
Black Lionhead Goldfish
Black Ranchu Goldfish
Black Ryukin Goldfish
Black Bubble Eye Goldfish

Setting Up the Perfect Black Moor Goldfish Tank
Tank Size Requirements
Despite their small size when purchased, Black Moors need room to grow:
Starting tank: 10 gallons minimum for 1-2 young Black Moors
Adult tank: 30+ gallons for 1-2 mature fish (they can grow to 10+ inches!)
Multiple fish: Add 10-20 gallons per additional Black Moor
Pro tip: Always plan for your fish’s adult size. Upgrading tanks is more difficult and stressful for your fish than starting with adequate space.

Essential Equipment for Black Moor Success
Creating the perfect environment requires:
Efficient filtration system – power filter with mechanical and chemical filtration
Gentle water movement – telescope eyes are sensitive to strong currents
Aquarium heater – set to 70°F to protect from temperature fluctuations
Gravel vacuum – for regular substrate cleaning
Water test kit – to monitor water parameters
Ideal Water Parameters
Black Moors thrive within these water conditions:

The Secret to Maintaining That Velvety-Black Color
Why Black Moors Sometimes Lose Their Color
Color loss is a common complaint among Black Moor owners. The main culprits include:
Excessive water temperature – warm water inhibits black pigment formation
Genetics – some Black Moors naturally fade with age
Poor nutrition – improper diet affects coloration
Water quality issues – dirty water stresses fish and affects color
Color-Preservation Strategies
To keep your Black Moor looking its best:
Maintain cooler water (65-70°F) – avoid placing tanks near heat sources
Avoid color-enhancing foods – these are formulated for red/orange goldfish
Perform regular water changes – 20% monthly at minimum
Use proper lighting – excessive bright light can fade coloration

Feeding Your Black Moor Goldfish Properly
The Ideal Black Moor Diet
Black Moors are omnivores with specific dietary needs:
Base diet: High-quality goldfish-specific pellets or flakes
Variety foods: Blanched vegetables (zucchini, peas)
Small amounts of fruit (banana, melon)
Occasional treats like bloodworms or brine shrimp

Feeding Schedule and Amount
Frequency: 2-3 small feedings daily rather than one large meal
Quantity: Only what your fish can consume in 2-3 minutes
Warning: Black Moors always appear hungry – resist overfeeding!
Important caution: Black Moors have compact digestive systems due to their egg-shaped bodies. Overfeeding can cause serious digestive problems and water quality issues.

Creating an Eye-Safe Aquascape
Due to their protruding eyes, Black Moors need special tank decoration considerations:
Substrate choice: Smooth gravel or sand (avoid sharp particles)

Plant selection: Anubias (robust and difficult to uproot)
Java fern (can be attached to decorations)
Hornwort (floating plant that won’t be disturbed)

Decorations: Smooth caves and ornaments
No sharp edges or points
Secure all decorations to prevent tipping
Design tip: Arrange plants and decorations with wide swimming spaces in between – telescope eyes make navigation challenging for Black Moors.

Choosing Compatible Tank Mates
Black Moors are peaceful but have special considerations when selecting companions:
Best Tank Mates
Other telescope-eyed varieties (similar swimming abilities)
Bubble eye goldfish (similar temperament and speed)
Other Black Moors (ideal companions)
Tank Mates to Avoid
Fast-swimming goldfish varieties (will outcompete for food)
Aggressive fish (may nip at flowing fins)
Tropical fish (different temperature requirements)
