Angelfish And Cichlids: Your Complete Guide To A Peaceful Community
Have you ever stood in front of an aquarium, mesmerized by the graceful glide of a Freshwater Angelfish, and then marveled at the vibrant, bustling energy of a tank full of cichlids? You’re not alone. Many aquarists dream of combining these stunning fish, but hesitate. You’ve probably heard the warnings about cichlid aggression and wondered if it’s even possible.
I’m here to tell you that not only is it possible, but creating a harmonious community of angelfish and cichlids can be one of the most rewarding experiences in the hobby. The secret isn’t luck; it’s knowledge. Forget the conflicting advice and confusion. This is your definitive roadmap.
In this comprehensive guide, we’ll bust the biggest myth about their family tree, walk you through the perfect tank setup, reveal the best (and worst) cichlid tank mates for your angelfish, and give you the pro-level tips to manage any squabbles. By the end, you’ll have the confidence to build the beautiful, active, and peaceful aquarium you’ve always wanted.
The Great Family Secret: Yes, Angelfish ARE Cichlids!
Let’s start with the biggest “a-ha!” moment for many aquarists. Freshwater Angelfish (Pterophyllum scalare) are not just compatible with some cichlids—they are cichlids! They belong to the Cichlidae family, just like Oscars, Jack Dempseys, and Rams.
So why all the confusion? The term “cichlid” often brings to mind the hyper-aggressive, rock-dwelling Mbuna from Africa’s Lake Malawi or the large, boisterous bruisers from Central America. Angelfish, hailing from the slow-moving, densely planted waters of the Amazon River Basin in South America, are a world apart in temperament.
They are generally more serene and stately, earning them the nickname “King of the Aquarium.” Understanding this distinction is the first step. You’re not trying to mix oil and water; you’re trying to create a community of cichlids with similar temperaments and needs. This is the foundation of our entire angelfish and cichlids guide.
Your Blueprint for Success: How to Set Up a Tank for Angelfish and Cichlids
A peaceful tank starts long before you add the fish. Creating the right environment is non-negotiable, and it’s where most beginners go wrong. Think of the tank as the foundation of a house—if it’s not solid, nothing you build on top will last. This is one of the most important angelfish and cichlids best practices.
Tank Size: Go Big or Go Home
When it comes to cichlids, even peaceful ones, territory is everything. A cramped tank is a recipe for stress, fighting, and disease. For a community of angelfish and other compatible dwarf cichlids, a 55-gallon tank is the absolute minimum.
However, if you truly want to see your fish thrive and minimize territorial disputes, I strongly recommend a 75-gallon tank or larger. The extra space provides more room for everyone to claim a spot, diffuses aggression, and makes maintaining stable water quality much easier. Remember, angelfish grow tall, so a standard or tall tank is better than a “long” one.
Perfecting Water Parameters
Angelfish and their compatible South American cichlid cousins share a love for similar water conditions. Replicating their natural habitat is key to their health and happiness. Here are the targets for your angelfish and cichlids care guide:
- Temperature: 78°F to 82°F (25°C to 28°C). Consistency is crucial, so use a reliable aquarium heater.
- pH: 6.5 to 7.5. Most captive-bred fish are adaptable, but they flourish in slightly acidic to neutral water.
- Hardness: Soft to moderately hard water is ideal.
- Water Quality: Pristine! Cichlids are sensitive to ammonia, nitrite, and high nitrates. A robust filter and weekly water changes of 25-30% are essential.
Aquascaping for Peace
This is where you can get creative and solve problems at the same time. A bare tank is a battlefield. A well-decorated one is a peaceful neighborhood with fences. The goal is to break lines of sight.
Use tall pieces of driftwood and tall, leafy plants like Amazon Swords, Vallisneria, and Java Fern. These create natural “walls” and barriers, allowing fish to retreat and feel secure in their own zones. Add caves, coconut huts, and flat stones on the substrate for dwarf cichlids like Rams to claim as their own. A well-planted tank not only looks stunning but is the single best tool for managing cichlid behavior.
Choosing the Right Neighbors: Compatible Cichlid Tank Mates
Now for the main event! Selecting the right tank mates is the most critical decision you’ll make. The key is to choose other cichlids from similar regions (South America) that are comparable in size and have a peaceful-to-semi-aggressive temperament. Here’s a look at some of the best—and worst—choices.
The “A-List” Companions
These cichlids are well-known for being great partners for angelfish in a properly sized tank. This is your go-to list for how to angelfish and cichlids successfully.
- German Blue or Bolivian Rams (Mikrogeophagus): These dwarf cichlids are a classic choice. They are colorful, stay small, and occupy the lower to mid-levels of the tank, leaving the upper regions for the angelfish.
- Keyhole Cichlids (Cleithracara maronii): Named for the keyhole-shaped spot on their side, these are one of the most peaceful cichlids available. They are shy and will appreciate a well-planted tank with plenty of hiding spots.
- Apistogramma Species: This genus of dwarf cichlids offers a stunning variety of colors and forms. Most “Apistos” are peaceful and make excellent tank mates, though they can become territorial when breeding.
- Festivums (Mesonauta festivus): A close relative of the angelfish, Festivums share a similar body shape and calm demeanor. They are a natural and excellent fit.
- Discus (Symphysodon): The majestic Discus can be kept with angelfish, but this is an “expert-level” pairing. Discus require even warmer, cleaner water and can be easily stressed. Proceed with caution and only if you’re an experienced aquarist.
The “Avoid at All Costs” List
Mixing these fish with your angelfish will almost certainly lead to disaster. Their needs and temperaments are completely incompatible.
- African Cichlids: This is the number one mistake. Cichlids from Lakes Malawi and Tanganyika require hard, alkaline water and are far too aggressive. They will bully, shred, and kill your angelfish.
- Large Central American Cichlids: Fish like Oscars, Jack Dempseys, Midas Cichlids, and Green Terrors get very large and are highly aggressive and predatory. They will see your angelfish as a snack.
- Convict Cichlids: While small, Convicts are notoriously aggressive, especially when breeding, which they do constantly. They will terrorize an entire community tank.
A Feast for All: Feeding Your Diverse Community
One of the great benefits of angelfish and cichlids from South America is that their dietary needs are very similar. They are omnivores that appreciate a varied diet rich in protein.
A high-quality cichlid pellet or flake should be the staple of their diet. Look for ingredients like krill, shrimp, and fish meal. To keep them in peak condition and color, supplement their diet 2-3 times a week with frozen or live foods.
Pro Tip: Great options include bloodworms, brine shrimp, daphnia, and mysis shrimp. This variety not only provides balanced nutrition but also encourages natural foraging behavior.
Troubleshooting Common Problems with Angelfish and Cichlids
Even in the best-planned tank, issues can arise. Don’t panic! Here’s how to handle the most common problems with angelfish and cichlids.
Taming the Beast: Managing Aggression
If you see chasing or nipping, the first step is to assess your setup. Is the tank big enough? Are there enough hiding spots and visual barriers? Often, simply adding more tall plants or a large piece of driftwood can solve the problem instantly.
Another great strategy is to add “dither fish.” These are peaceful, fast-moving schooling fish like larger Tetras (Bleeding Hearts, Congo Tetras) or Denison Barbs. Their constant, calm movement signals to the cichlids that there are no predators around, reducing anxiety and aggression.
Recognizing and Handling Breeding Behavior
When a pair of angelfish or dwarf cichlids decides to breed, their protective instincts will kick in, and they’ll become very territorial. You’ll see them meticulously cleaning a flat surface (a leaf, a slate, or a piece of driftwood) and chasing away any fish that comes near.
If the aggression becomes too intense for the other tank mates, you have two options: add more visual barriers around their chosen site or, if you want to raise the fry, move the pair to a dedicated 20-gallon breeding tank.
A Word on Sustainable Angelfish and Cichlids
As responsible aquarists, we should also consider our impact. The good news is that the vast majority of angelfish and their popular cichlid tank mates are commercially bred. Choosing captive-bred fish is the most eco-friendly and sustainable angelfish and cichlids practice.
Captive-bred fish are hardier, already accustomed to aquarium life, and don’t deplete wild populations. Support your local fish stores and reputable breeders who prioritize the health and ethical treatment of their animals. It’s a win for you, the fish, and the environment.
Frequently Asked Questions About Angelfish and Cichlids
Can I keep just one angelfish with other cichlids?
Yes, and sometimes it’s even preferable! A single angelfish can be a beautiful centerpiece without the potential for pairing up and breeding aggression. Alternatively, a group of six or more can work well, as aggression is spread out among the group, and no single fish is targeted.
What size tank do I really need for angelfish and compatible cichlids?
We can’t stress this enough: a 55-gallon tank is the bare minimum for a small community. For a truly thriving, peaceful environment with room for error, a 75-gallon tank or larger is highly recommended. The extra water volume helps keep parameters stable and gives everyone the space they need.
Why are my angelfish fighting with my rams?
This is a classic example of one of the common problems with angelfish and cichlids. If this happens, check three things first: tank size (is it too small?), aquascaping (are there enough hiding spots and visual breaks?), and breeding (has one of the pairs laid eggs?). Often, adding more plants or caves can resolve the conflict by allowing them to establish separate territories.
What non-cichlid fish can I keep with them?
Excellent question! Peaceful, robust tank mates can round out your community. Great choices include schools of larger tetras (avoid small ones like Neons, which adult angelfish may eat), Corydoras catfish for the bottom, Bristlenose Plecos for algae control, and peaceful Gouramis.
Your Journey to a Thriving Tank Starts Now
Creating a beautiful aquarium filled with both angelfish and cichlids is an achievable dream. It’s a project that rewards careful planning and a little bit of knowledge with a truly spectacular display of color, grace, and personality.
Remember the keys to success: a spacious tank, plenty of visual barriers, stable water conditions, and—most importantly—a carefully curated list of peaceful, compatible tank mates. You have the blueprint and the best practices at your fingertips.
Now, go forth and build that stunning community you’ve been dreaming of. Happy fishkeeping!
