There’s nothing quite like the elegance of a Freshwater Angelfish gliding through an aquarium. With their long, flowing fins and regal presence, they are the centerpiece of many home aquariums. But as you stand in front of your beautiful 55-gallon tank, a common question probably pops into your head: “What other fish can I actually keep with them?”
You’ve likely heard the whispers—that angelfish are cichlids, and cichlids can be, well, a little feisty. It’s a valid concern! Choosing the wrong tank mates can lead to stress, fin nipping, and a chaotic tank instead of a peaceful underwater sanctuary.
But don’t worry. I promise that by the end of this guide, you will have the confidence and knowledge to select the perfect angelfish tank mates 55 gallon aquarists dream of. We’ll unlock the secrets to a balanced and beautiful community tank.
In this complete guide, we will dive deep into understanding angelfish behavior, explore the absolute best (and worst!) tank mates, and give you actionable tips on setting up your tank for guaranteed success. Let’s build your dream aquarium together!
Understanding Angelfish: The Key to a Peaceful Tank
Before we even think about adding other fish, let’s talk about the stars of the show: your angelfish. Understanding their personality is the first and most crucial step in this process. Think of it as getting to know your roommate before they move in!
Angelfish (Pterophyllum scalare) are cichlids from South America. While they are known as one of the more peaceful cichlids, they still have that classic cichlid DNA. This means they can be territorial, especially as they mature and form breeding pairs. A 55-gallon tank is a fantastic size because it provides enough room for them to claim a little space of their own without dominating the entire aquarium.
Here are a few key personality traits to remember:
- Semi-Aggressive Nature: They aren’t bullies by nature, but they will defend their territory. This aggression often peaks if a pair decides to spawn.
- They Get Big: Those tiny angels at the store can grow up to 6 inches long and 8-10 inches tall! This height is why tall tanks like a 55-gallon are ideal.
- They Can Be Predators: It’s not personal, it’s instinct. Any fish small enough to fit in an adult angelfish’s mouth (like a Neon Tetra) is at risk of becoming an expensive snack.
Keeping these traits in mind will make the selection process in this angelfish tank mates 55 gallon care guide intuitive and successful.
The Best Angelfish Tank Mates 55 Gallon Guide: Top Picks for Harmony
Alright, let’s get to the fun part! Choosing the right companions is all about balance. We need fish that are peaceful, won’t nip at those gorgeous angelfish fins, and are too large to be considered a meal. This section is your go-to angelfish tank mates 55 gallon guide for building a tranquil community.
Bottom Dwellers: The Unsung Heroes
These fish live in a different “neighborhood” of the tank, so they rarely compete with angelfish for space. They are the perfect, low-drama roommates.
Corydoras Catfish: I can’t recommend these little guys enough! Corys are peaceful, busy-bodied bottom dwellers that will help clean up leftover food. They are social, so you’ll want a group of at least 6. Don’t worry—they are perfect for beginners!
- Pro Tip: Opt for slightly larger species like Sterbai, Bronze, or Peppered Corys. They are robust and a joy to watch.
Bristlenose Pleco (Ancistrus): If you want an algae-eater, the Bristlenose is your best bet. Unlike the Common Pleco that can grow to over a foot long, the Bristlenose maxes out at a manageable 4-5 inches. They are fantastic algae eaters and generally keep to themselves.
Mid-Level Swimmers: Peaceful Companions
These fish will share the main swimming space with your angelfish, so choosing peaceful, non-threatening species is critical. Here are some of the best practices for this tank zone.
Larger Tetras: This is where many aquarists make a mistake. Tiny tetras are a no-go! You need to choose deeper-bodied, faster-swimming tetras that won’t be seen as food.
- Black Skirt Tetras: A classic and hardy choice. Their deeper body shape makes them an unappealing target.
- Rummy Nose Tetras: These are excellent “indicator” fish. Their bright red nose will fade if water conditions are poor! Keep them in a school of 6 or more.
- Lemon Tetras: A beautiful, often-overlooked tetra that brings a splash of subtle color.
Dwarf Cichlids: Yes, you can keep other cichlids with angels! The key is choosing peaceful dwarf species. They tend to stick to the lower-mid levels of the tank.
- Bolivian Rams: Hardier and generally more peaceful than their German Blue cousins, Bolivian Rams are a fantastic choice. They are curious and have tons of personality.
- German Blue Rams: Stunningly beautiful, but more sensitive to water quality. Only add these if your tank is well-established and stable.
Gouramis: Certain types of Gouramis can be a great fit. Their graceful swimming style mirrors that of angelfish. Pearl Gouramis are an excellent, peaceful option known for their beautiful patterns.
Fish to AVOID: A Recipe for Disaster in Your Angelfish Tank
Just as important as knowing what to add is knowing what to avoid. Adding the wrong fish is one of the most common problems with angelfish tank mates 55 gallon setups. Save yourself the heartache and steer clear of these species.
The Fin Nippers
Angelfish have long, flowing fins that are an irresistible target for nippy fish. This is incredibly stressful and can lead to infections.
- Tiger Barbs: The classic fin nipper. Do not mix them with angelfish under any circumstances.
- Serpae Tetras: While beautiful, they have a reputation for being nippy and aggressive.
- Most other Barbs: It’s generally a good rule of thumb to be cautious with most barbs.
The Bullies
Your angelfish might be semi-aggressive, but they are no match for truly aggressive cichlids or other large, boisterous fish.
- Large Cichlids: Oscars, Jack Dempseys, Green Terrors, and African Cichlids will terrorize and likely kill your angelfish.
- Convict Cichlids: They are small but incredibly aggressive, especially when breeding.
The Potential Snacks
Remember our rule: if it fits in an adult angelfish’s mouth, it will eventually end up there.
- Neon Tetras & Cardinal Tetras: While beautiful, they are the perfect size for an angelfish snack. It might not happen today, but it’s a risk you don’t want to take.
- Guppies & Endlers: Too small and flashy. They will be hunted.
- Dwarf Shrimp: Cherries, Amanos, and others will be considered a delicious, expensive treat.
How to Set Up Your 55-Gallon Tank for Success
Knowing how to angelfish tank mates 55 gallon setups should be arranged is just as important as the fish you choose. A well-planned environment dramatically reduces stress and aggression. Think of it as good interior design for your fish!
Aquascape for Peace
The goal is to break up sightlines and create distinct territories. A bare tank is a recipe for conflict.
- Go Vertical: Angelfish love vertical space. Use tall plants (like Amazon Swords, Vallisneria) and tall pieces of driftwood. This allows them to feel secure and creates natural barriers.
- Create Hiding Spots: Use caves, dense plant thickets, and driftwood to give other fish places to retreat and feel safe. This is especially important for shyer species like Rams.
- Leave Open Space: Don’t overcrowd the decor. Ensure there is an open area in the front of the tank for swimming.
The Golden Rule of Introduction
This is one of the most valuable angelfish tank mates 55 gallon tips I can give you: add your angelfish last, or at least add all the fish when they are young and at the same time.
If you add angelfish to an empty tank first, they will claim the entire 55 gallons as their territory. Any fish added later will be seen as an intruder. By adding the more peaceful dither fish and bottom dwellers first, territories are already established, and the angels are less likely to become bullies.
Solving Common Problems with Angelfish Tank Mates
Even with perfect planning, issues can sometimes arise. Don’t panic! Here’s how to troubleshoot some common challenges.
Problem: My angelfish formed a pair and are now terrorizing the tank!
This is a classic angelfish behavior. When they are ready to breed, they become extremely territorial. You have a few options: move the breeding pair to their own tank (a 20-gallon high is great for this), add a tank divider to protect the other fish, or re-scape the tank significantly to break up the established territory.
Problem: My tank mates are always hiding.
This is a sign of stress. First, check your water parameters. Second, observe for any subtle bullying from the angelfish. Third, and most likely, they may need more cover. Try adding more plants or driftwood to make them feel more secure.
Sustainable & Eco-Friendly Angelfish Tank Mates
As responsible aquarists, we can make choices that benefit not only our tanks but the planet, too. The concept of sustainable angelfish tank mates 55 gallon setups is about making conscious decisions.
The best thing you can do is choose captive-bred fish. The vast majority of the recommended tank mates (Corydoras, Bristlenose Plecos, Rams, many Tetras) are readily available as captive-bred. This reduces the pressure on wild populations and their native habitats in the Amazon.
By supporting local fish stores and reputable breeders who prioritize health and sustainability, you contribute to a more eco-friendly angelfish tank mates 55 gallon community. A well-planted tank also creates a more balanced ecosystem, which can reduce the need for large, frequent water changes, further conserving resources.
Frequently Asked Questions About Angelfish Tank Mates
How many angelfish can I keep in a 55-gallon tank with other fish?
For a peaceful community, your best bet is to keep a single mated pair. If you want a group, start with 4-5 young angelfish and be prepared to re-home some if a pair forms and becomes overly aggressive. A single angelfish can also be kept and will often be less territorial.
Can I keep snails or shrimp with angelfish?
Snails are a great option! Larger species like Mystery Snails or Nerite Snails are generally safe and excellent cleaners. Most shrimp, however, are not. Even larger Amano shrimp are at risk of being picked on or eaten by a full-grown angelfish.
What is the absolute safest tank mate for an angelfish?
If you’re looking for the most foolproof, drama-free companion, it has to be a school of Corydoras catfish. They live in a different part of the tank, are incredibly peaceful, and are too large and armored to be eaten. They are the perfect neighbor!
Your Peaceful Aquarium Awaits
Whew, that was a lot of information! But now you are armed with a complete angelfish tank mates 55 gallon care guide. You understand their temperament, know which fish make great friends (and which to avoid), and have the blueprint for setting up your tank for success.
