An Introduction to Macaw Cichlids

Macaw cichlids, scientifically named Hypsophrys nicaraguensis, are native to the lakes and tributaries of Nicaragua and Costa Rica. These New World cichlids get their common name from their vibrant coloration resembling the hues of tropical macaws.

Some quick facts about macaw cichlids:

• Average Size: 6-8 inches
• Lifespan: 10-12 years with proper care
• pH Range: 7.0-8.5
• Temperature Range: 70-82°F
• Diet: Omnivorous, eats variety of live and prepared foods
• Temperament: Aggressive toward conspecifics, moderately aggressive to tankmates
• Care Level: Moderate to advanced – requires large tank
• Appearance: Bright yellows, greens, blues, reds, orange; black bars

Now that you know a bit about their background, let’s go over ideal tank setup and water parameters for these lively cichlids.

Aquarium Setup for Macaw Cichlids

Macaw cichlids are active, robust fish that need ample tank space to thrive. Here are the basic requirements for their habitat:

Minimum Tank Size

Due to their large adult size and aggressive nature, macaw cichlids require at least a 55 gallon aquarium. Bigger is always better – a 75 gallon or larger tank is ideal.

Aquascape Considerations

Leave plenty of open swimming space for these energetic fish. Using a fine sand substrate mimics their natural environment.

Incorporate several rock formations and cave-like structures made from stone or clay pots to provide sight breaks and territorial domains.

Driftwood branches and roots make good dither areas to help diffuse aggression. Live plants like Anubias and Java Fern can be added, but may get uprooted.

Filtration Needs

Macaw cichlids are big waste producers. Use robust external canister filtration rated for at least 2-3x the tank volume to maintain pristine water.

Powerful water flow helps mimic their native habitat. But avoid direct high-pressure outflow blasting the fish.

Heating & Lighting

Standard aquarium heaters are necessary to keep water within the 78-82°F temperature range macaws prefer.

Moderate aquarium lighting around 8 hours daily works well. Ensure lights don’t shine directly into tank and cause excess algae.

Other Equipment

A sturdy lid or canopy prevents jumping and supports strong overhead lighting. Consider adding air stones for supplemental oxygenation.

Maintaining Proper Water Parameters for Macaw Cichlids

Macaw cichlids do best in clean, alkaline freshwater mimicking their natural environment:

• Temperature: 78-82°F
• pH: 7.4-8.2
• Hardness: Hard. 12-20 dGH range.
• Nitrogen cycle: Fully cycled tank is essential

Use crushed coral or aragonite substrate to naturally buffer pH and hardness. Perform 25-40% weekly water changes to control nitrate buildup. Add buffers as needed to maintain pH in the ideal range.

Test water parameters frequently to ensure ammonia and nitrites read zero, and nitrates stay below 40 ppm. Use chemical filtration like activated carbon to absorb organics.

Feeding Your Macaw Cichlids

Macaw cichlids are omnivores in the wild, foraging on worms, crustaceans, insects, and plant matter. Replicate this varied diet in your aquarium for optimal health:

• High-quality pellets should form the nutritional base of their diet. Look for formulas containing 30-40% protein. Offer 2-3 times daily.
• Supplement with frozen and live foods like bloodworms, brine shrimp, mosquito larvae, crickets, chopped seafood and greens. Help bring out their colors!
• Let them graze on algae wafers as well to round out their diet.
• Fast 1 day per week to aid digestion and prevent obesity.

Feed juveniles smaller but more frequent meals 4-6 times daily. Adults can eat larger portions 2-3 times per day. Provide only as much food as they can consume within 2-3 minutes, and remove any excess to keep water clean.

Macaw Cichlid Tankmates & Compatibility

Macaw cichlids are moderately aggressive fish that can be kept with select tankmates but may fight conspecifics. Here are some compatibility considerations:

Conspecific Compatibility

Unless breeding, only keep one macaw cichlid per tank. They are fiercely territorial toward their own kind. Introduce tankmates first so they don’t view them as invaders.

Good Tankmate Options

Some suitable options include:

• Silver dollars
• Larger tetras like congo and emperor
• Medium-sized barbs like tiger and rose line sharks
• Plecostomus and clown loaches
• Larger gouramis like pearl and moonlight

Questionable Tankmates

Approach with caution:

• Smaller cichlids like convicts, firemouths, texas, etc.
• Aggressive barbs like red tailed sharks
• Catfish like pictus and upside down
• African cichlids like kenyi, auratus, etc.

Avoid Keeping Macaw Cichlids With:

• Small, delicate community fish they may eat
• Ornate fish with flowing fins like bettas and guppies
• Highly aggressive cichlids like flowerhorn or jaguar
• Shrimp, snails, or other organisms they see as prey

Research any potential tankmates thoroughly before introducing. Never add new fish right away. Quarantine, acclimate slowly, and observe closely when first mixing species. Have backup tank space available if aggression arises.

Typical Macaw Cichlid Behavior & Personality

Macaw cichlids exhibit behaviors typical of New World cichlids:

• Curious and intelligent – they interact with owners
• Energetic and fast-moving
• Moderate aggression toward tankmates
• High conspecific aggression – don’t mix more than one
• Territorial, especially when spawning
• Occasional substrate digging
• Prone to jumping – secure tank lids are key!

Expect males to intensify in color and display dominance behaviors like flaring gills, chasing, and frontal displays.

Interestingly, macaw cichlids are facultative mouthbrooders – they pick up eggs in their mouths when threatened but don’t carry developing fry.

Breeding & Caring for Macaw Cichlid Fry

While tricky, breeding macaw cichlids is possible in a dedicated tank. Here’s an overview:

• Condition mature breeding pair with live foods
• Setup 75+ gallon breeding tank with flat rocks for spawning sites
• Perform large water change to trigger spawning behavior
• Hundreds of small yellow eggs will be laid and fertilized
• Parents will pick up eggs if they feel threatened
• Move parents once eggs are laid
• Eggs hatch in 3-5 days. Free-swimming fry emerge in 6-8 days
• Feed infusoria then newly hatched brine shrimp
• Fry grow slowly – it takes 9+ months to reach maturity
• Juveniles are aggressive – separate once 1.5-2 inches long

Raising the tiny but pugnacious fry takes diligence. Maintain meticulous water quality and frequently feed microworms, brine shrimp nauplii, and finely crushed quality pellets. Prepare to separate aggressive juveniles as they grow.

Typical Lifespan & Health Concerns

In clean, well-maintained home aquariums, macaw cichlids generally live 8-12 years. Ensure they are ethically wild-caught or tank raised.

Some common health issues to watch for include:

• Ich (white spot disease)
• Fin rot or tail rot
• Bloating due to constipation
• Hole in the head disease (HEX)
• Malnutrition from inappropriate diet

Quarantine new specimens for 2-4 weeks and treat any illness before adding to your main tank. Maintain robust tank filtration and cleaning routines. Vary their diet and closely observe all fish to catch problems early.
