Cichlids are some of the most exciting and rewarding fish you can add to your freshwater collection. Their bright colors, bold patterns, and lively personalities make them stand out from typical community fish. Many hobbyists fall in love with cichlids because they’re interactive, intelligent, and always on the move. However, they also come with unique care requirements that beginners must understand before diving in.
Unlike small community fish such as tetras or guppies, cichlids are known for their territorial behavior and dominant personalities. They require specific water parameters, specialized tank setups, and carefully chosen tankmates. When you understand how to support their instincts—and how to prevent the aggression they are famous for—you can enjoy a beautiful, thriving cichlid tank that becomes the highlight of your home.
This guide breaks down the basics of choosing your first cichlid, managing aggression, setting up a proper tank, maintaining water quality, and feeding them a balanced diet.
Choosing the Right Cichlid for Beginners
Start by researching the adult size, aggression levels, and water needs of different cichlid species to ensure compatibility and success.
African Cichlids
Most beginners are drawn to African cichlids, especially species from:
- Lake Malawi
- Lake Tanganyika
- Lake Victoria
These fish are bursting with color—yellows, blues, oranges, reds—and stay active throughout the day. African cichlids typically prefer:
- Higher pH (7.8–8.6)
- Harder water
- Rock-heavy environments
- Larger tanks are due to their territorial nature.
Within African cichlids, beginners often choose:
- Mbuna (rock-dwellers; active, colorful, but often aggressive)
- Peacocks (less aggressive, stunning coloration)
- Haps (larger, open-water swimmers)
Each group has its own personality and parameter needs, so research is key.
New World Cichlids
Some beginners also explore American/New World cichlids, like:
- Angelfish
- Bolivian rams
- Apistogrammas
- Keyhole cichlids
- Firemouth cichlids
These species are more peaceful than African cichlids and thrive in planted tanks. They usually prefer:
- Lower to mid-range pH (6.0–7.5)
- Softer water
- More structure for territory, but not as rock-heavy
While species like oscars, Jack Dempseys, and flowerhorns are also New World cichlids, they are not beginner-friendly due to size, aggression, and huge tank requirements.
Do Your Research Before Buying
Before bringing home any cichlid:
- Learn the adult size
- Check aggression levels
- Confirm water parameter needs.
- Make sure your tank is the appropriate size.
- Understand if they’re compatible with tankmates.
Cichlids are rewarding fish, but picking the wrong species for your setup almost always leads to stress—for both you and the fish.
Managing Aggression the Right Way
Aggression is the most well-known part of keeping cichlids, but it doesn’t have to make your tank chaotic. Most aggression comes from:
- Territory defense
- Breeding behavior
- Size mismatches
- Too few hiding spots
- Too much open space
Understanding how to structure the tank and manage group dynamics helps prevent one fish from dominating the others.
Provide Plenty of Hiding Spots
Cichlids feel safer when they have:
- Rock caves
- Overhangs
- Line-of-sight breaks
- Plant clusters (for non-digging species)
- Driftwood structures
This reduces how often fish see one another, thereby lowering territorial behavior.
Overstocking, when done correctly in a larger tank (40+ gallons), can help spread out aggression and create a more peaceful environment for your cichlids.
While it seems strange, slightly overstocking an African cichlid tank can actually reduce aggression. When there are more fish, no single individual can claim the entire tank. This spreads out aggression and prevents constant bullying.
Essential rules for this method:
- Use a larger tank (40+ gallons for most species)
- Add high-quality filtration to handle the bioload.
- Introduce fish all at once when possible.e
Avoid Mixing Incompatible Species
Mixing fish from different lakes or regions can cause:
- Parameter mismatches
- Extreme aggression
- Stress from unfamiliar behaviors
Stick to species with similar needs and temperaments.
Watch for Bullying
Signs include:
- Chasing one specific fish repeatedly
- Torn fins
- Hiding, refusing to eat
- Staying in corners or near the surface
If one fish is consistently targeted, rearranging the tank or adding more hiding spaces can help. In severe cases, the aggressor may need to be separated temporarily.
Tank Setup for Cichlids
Cichlids thrive in tanks designed explicitly for their instincts. A well-planned setup prevents aggression, improves health, and highlights their color and activity.
Tank Size
For most beginner-friendly cichlids:
- African cichlids: 40 gallons minimum
- Angelfish: 20+ gallons (tall tank preferred)
- Rams/Apistos: 20 gallons for a pair
- Dwarf cichlids: 10–20 gallons, depending on species
The more space they have, the easier it is to manage territorial behavior.
Substrate
Some cichlids dig heavily, especially African mbuna. Sand or fine gravel is ideal for these species. New World cichlids generally tolerate a wider range of substrate options, including planted tank soils.
Aquascaping
African cichlids love:
- Rock piles
- Slate caves
- Stacked structures
- Hardscape-heavy setups
New World cichlids prefer:
- Driftwood
- Leaf litter
- Live plants (except species that dig)
- Moderate decorations
Always ensure your stone structures are stable—cichlids love to rearrange.
Filtration
Cichlids produce significantly more waste than many other fish. Choose:
- A canister filter
- A high-quality HOB filter
- Or a combination of both
Aim for strong flow, high oxygenation, and mechanical + biological filtration.
Water Quality Requirements
Keeping water parameters is essential for cichlids to thrive. They are messy eaters and frequent diggers, which can stir up debris and place extra strain on your filter.
Weekly Water Changes
Perform 20–40% water changes weekly depending on:
- Tank size
- Stocking level
- Filter strength
This keeps nitrates low and water clarity high.
Monitor Parameters
Most cichlids prefer:
- Stable pH
- Ammonia: 0 ppm
- Nitrite: 0 ppm
- Nitrate: Under 20–40 ppm, depending on species
African cichlids generally like:
- Higher pH (7.8–8.6)
- Hard water
While South American cichlids prefer:
- Softer water
- Lower pH (6.0–7.2)
Test your water weekly until you learn your tank’s patterns.
Avoid Rapid Changes
Cichlids are sensitive to sudden shifts in:
- pH
- Temperature
- KH and GH
- Nitrate levels
Make changes slowly to prevent shock and stress.
Feeding and Nutrition
A balanced diet brings out the best color and growth in cichlids. Different species have different dietary needs, so it’s essential to know whether yours are:
- Carnivores
- Omnivores
- Herbivores
Pellets as a Staple
Choose a high-quality pellet designed for:
- African cichlids
- South American cichlids
- Dwarf cichlids
(depending on what you keep)
Pellets ensure consistent nutrition and are easy to portion.
Protein-Rich Foods
For omnivores and carnivores:
- Frozen brine shrimp
- Krill
- Bloodworms (sparingly)
- Mysis shrimp
These foods support growth and vibrant color.
Avoid Excess Protein for Herbivores
Many African mbuna are herbivores, and too much protein can cause:
- Bloating
- Digestive problems
- Malawi bloat (dangerous and often fatal)
Stick to algae wafers, spirulina-based foods, and plant-based flakes for these species.
Feed Moderately
Cichlids are enthusiastic eaters, but overfeeding causes:
- Poor water quality
- Excess waste
- Digestive issues
Feed them small portions 1–2 times per day.
Are Cichlids Right for Beginners?
Absolutely—if you plan. Cichlids are incredibly rewarding and can take your hobby to the next level. They’re full of personality, stunning to look at, and fascinating to observe.
With the proper setup, you can enjoy:
- Bright colors
- Natural behaviors
- Active displays
- Unique social dynamics
When you understand their needs and properly prepare your tank, cichlids quickly become among the most enjoyable fish to keep.
Final Thoughts
Cichlids offer a level of excitement, color, and personality that many other freshwater fish can’t match. While they require more attention to tank setup, water quality, and compatibility, the payoff is worth it. By choosing the right species, creating a habitat that matches their instincts, managing aggression proactively, and feeding them a balanced diet, you can enjoy a thriving cichlid community even as a beginner.
Plan, be patient, and give your new fish the environment they need—and they’ll reward you with nonstop activity and a tank full of life.
