Tank Mates Angelfish – The Complete Compatibility Guide For A Peaceful
There’s nothing quite like the elegance of a Freshwater Angelfish gliding through an aquarium. With their diamond-shaped bodies and long, flowing fins, they are truly the kings and queens of the freshwater world. I bet you agree. But as many aquarists discover, finding the right tank mates angelfish can feel like a high-stakes puzzle.

I promise you, it doesn’t have to be this way. With a bit of knowledge and planning, you can absolutely create a stunning, harmonious community aquarium with your angelfish as the centerpiece. You can have a tank that’s bustling with life, color, and peaceful activity.
In this comprehensive tank mates angelfish guide, we’re going to walk through everything you need to know. We’ll cover the absolute best (and worst!) companions, how to set up your tank for success, and a step-by-step method for introducing new fish without causing chaos. Let’s build that beautiful aquarium together!
Understanding Angelfish Temperament: The Key to Success
Before we even think about other fish, let’s talk about the star of the show. Angelfish (Pterophyllum scalare) are cichlids, and that one word tells us a lot. Cichlids are known for being intelligent, personable, and, yes, a little bit territorial.
Think of them not as aggressive, but as semi-aggressive. They aren’t looking for a fight, but they will establish a pecking order and defend their personal space, especially as they mature. A cute, quarter-sized juvenile angelfish is a very different animal from a full-grown adult with a 6-inch body and a desire to breed.
The secret to success is working with their nature, not against it. This means providing:
- A Tall Tank: Angelfish are vertically oriented. A standard 29-gallon tank is the absolute minimum for a pair, but a 55-gallon or larger is much better for a community. The height gives them room to swim comfortably.
- Plenty of Plants and Decor: Tall plants like Amazon Swords and Vallisneria, along with driftwood, create visual barriers. This breaks up lines of sight and allows fish to have their own “neighborhoods,” which dramatically reduces tension.
Understanding these core needs is the first step in our tank mates angelfish best practices. A happy angelfish is a much more peaceful neighbor.
The Best Tank Mates for Angelfish: Your Go-To List
Alright, let’s get to the fun part! Choosing the right companions is all about finding fish that won’t bother your angels, and won’t be bothered by them. We’re looking for fish that are peaceful, not prone to fin-nipping, and too large to be considered a snack.
Top-Dwelling & Mid-Dwelling Companions
These fish share the main swimming space with your angelfish, so temperament is key.
- Corydoras Catfish: An absolute classic pairing! Corys are peaceful, busy-body bottom dwellers that will completely ignore your angelfish, and vice-versa. They are fantastic for beginners and help keep your substrate clean. Get a group of at least 6.
- Larger Tetras: This is where people often go wrong. Avoid small tetras like Neons! Instead, opt for larger, more robust species like Black Skirt Tetras, Rummy Nose Tetras, or Bleeding Heart Tetras. In a proper school of 6-8, they are confident and fast enough to coexist peacefully.
- Bristlenose Plecos: Unlike the common pleco that gets enormous, the Bristlenose stays a manageable 4-5 inches. They are armored, peaceful algae-eaters that are fantastic for keeping your tank glass and decor clean. A true workhorse for any angelfish tank.
- Dwarf Gouramis: This can be a great pairing, but with a small caveat. Gouramis can sometimes be territorial themselves. In a large enough tank (55+ gallons) with plenty of visual barriers, a single Dwarf Gourami and your angelfish can coexist beautifully. Avoid keeping multiple male gouramis together.
- Bolivian Rams: These peaceful dwarf cichlids are a wonderful choice. They are less aggressive and demanding than their German Blue Ram cousins and stick mostly to the bottom and mid-levels of the tank, leaving the top half for your angels.
Bottom-Dwelling Cleanup Crew
Having a dedicated cleanup crew offers one of the biggest benefits of tank mates angelfish—a cleaner, healthier, and more dynamic ecosystem.
- Kuhli Loaches: These quirky, eel-like fish are fantastic scavengers. They are nocturnal and shy, so you might not see them often, but they do an amazing job of finding leftover food. They are completely peaceful and will never bother an angelfish.
- Otocinclus Catfish: If you have a well-established, planted tank, a small school of “Otos” is a great addition. They are tiny, dedicated algae eaters. Important: Add them only to a mature tank with stable water parameters, as they can be sensitive.
Fish to AVOID: A Recipe for Disaster
Just as important as knowing what to add is knowing what to avoid. Choosing the wrong tank mate is the number one cause of common problems with tank mates angelfish. Please, for the health of your fish, steer clear of these.
Fin Nippers and Bullies
Angelfish have long, flowing fins that are an irresistible target for nippy fish. This is incredibly stressful and can lead to secondary infections.
- Tiger Barbs: The poster child for fin nippers. Do not mix them with angelfish under any circumstances.
- Serpae Tetras & Black Phantom Tetras: While beautiful, they have a well-deserved reputation for nipping.
- Most other Barbs: Species like the Denison Barb (Roseline Shark) get too large and active for a typical angelfish setup.
Fish That are Too Small
Here’s a simple rule: if a fish can fit in an adult angelfish’s mouth, it will eventually end up there. Angelfish are opportunistic predators.
- Neon Tetras & Cardinal Tetras: This is the most common and heartbreaking mistake. They may be fine when the angels are young, but one day you’ll wake up and your school of neons will have vanished.
- Guppies & Endlers: Their flashy fins and small size make them a perfect target. Avoid them completely.
- Shrimp: Except for maybe the largest Amano shrimp, most dwarf shrimp (like Cherry Shrimp) will be viewed as an expensive, delicious snack.
Other Aggressive Fish
Don’t mix cichlids from different parts of the world, and don’t try to house your angels with tank busters.
- African Cichlids: They require completely different water parameters (hard, alkaline water) and are far too aggressive.
- Oscars, Jack Dempseys, Green Terrors: These large Central/South American cichlids are much more aggressive and will bully or kill your angelfish.
How to Tank Mates Angelfish: A Step-by-Step Introduction Guide
Knowing how to add new fish is critical. You can’t just drop them in and hope for the best! Following this process will dramatically increase your chances of success.
- Quarantine, Quarantine, Quarantine! I can’t stress this enough. Every new fish, no matter where you got it, should be kept in a separate quarantine tank for 2-4 weeks. This prevents you from introducing diseases like Ich into your main display tank.
- Add Angelfish Last (or Young): The best strategy is to add your other community fish (like tetras and corys) first. Let them get established. Then, add your angelfish as small juveniles. This way, the angels grow up with their tank mates and are less likely to see them as intruders or food.
- Do a Rescape: Before adding the new fish, move the decorations around. Change the layout of the plants and driftwood. This resets all the established territories and forces every fish, new and old, to find their own space. It’s a simple trick that works wonders.
- Feed Before You Add: A full fish is a happy fish. Give your current residents a good meal right before you introduce the new arrivals. This distracts them and reduces the likelihood of immediate aggression.
- Monitor Closely: Stay by the tank for the first hour or so. Watch for any serious chasing or bullying. A little bit of posturing is normal, but constant harassment is a sign that the pairing won’t work.
The Sustainable Angelfish Community: Eco-Friendly Best Practices
Being a great aquarist also means being a responsible one. Creating a sustainable tank mates angelfish setup is not only better for the planet but also creates a healthier environment for your fish. This is a core part of our philosophy here at Aquifarm.
Consider these eco-friendly tank mates angelfish tips:
- Choose Captive-Bred Fish: Whenever possible, purchase fish that were bred in captivity rather than caught from the wild. This reduces the pressure on wild populations and ensures you get a healthier fish that is already accustomed to aquarium life. Nearly all the recommended tank mates here are widely available as captive-bred.
- Embrace Live Plants: A heavily planted tank is the most natural and stable environment. Plants act as a natural filter, consuming nitrates and oxygenating the water. This reduces your reliance on large, frequent water changes, saving water and creating a more balanced ecosystem.
- Feed Responsibly: Overfeeding is the number one cause of poor water quality. Feed your fish only what they can consume in about 60 seconds, once or twice a day. This reduces waste, keeps the water cleaner, and is healthier for your fish.
Frequently Asked Questions About Tank Mates Angelfish
What is the best tank size for angelfish and their tank mates?
For a pair of angelfish alone, a 29-gallon “tall” tank is the minimum. However, if you want a community tank with other fish, you should really start with a 55-gallon tank. This provides enough horizontal swimming room for other schools of fish and enough vertical space for the angels, reducing territorial disputes.
Can angelfish live with shrimp or snails?
Snails are generally safe! Nerite Snails and Mystery Snails are great additions and are too large to be eaten. Shrimp are a different story. Most dwarf shrimp, like Red Cherry Shrimp, will be hunted and eaten. You might have success with larger Amano Shrimp or Vampire Shrimp in a heavily planted tank, but it’s always a risk.
Should I get a single angelfish, a pair, or a group?
Angelfish can be kept singly and will often be the “wet pet” of the tank. If you want a pair, the best method is to buy a group of 5-6 unrelated juveniles. As they grow, a pair will naturally form. Once a pair has formed, they will likely become very aggressive towards the other angels, so you will need a plan to re-home the others. Do not buy two random adult angelfish and expect them to pair up; they will likely fight.
Your Peaceful Angelfish Community Awaits
