What Fish Go Well With Angelfish – A Complete Guide To Peaceful Tank
There’s a reason Pterophyllum scalare, the freshwater angelfish, is called the “king of the aquarium.” With their elegant, diamond-shaped bodies and long, flowing fins, they bring a sense of grace and majesty to any tank. But as many aquarists quickly discover, these kings can have a bit of a temper.
You’ve brought home your beautiful angelfish, and now you’re staring at an empty-ish tank, wondering, “what fish go well with angelfish?” It’s a question that can feel overwhelming. You’ve heard horror stories of tiny fish disappearing overnight or a once-peaceful tank turning into a warzone.
Let me promise you this: creating a harmonious community tank with angelfish is not only possible, it’s incredibly rewarding. You just need the right knowledge. This is your complete what fish go well with angelfish guide, built from years of experience, to help you choose the perfect companions for your prized fish.
In this article, we’ll dive deep into understanding your angelfish’s personality, the golden rules for choosing tank mates, a “best of the best” list of compatible species, and—just as importantly—which fish to avoid at all costs. Let’s build that stunning, peaceful aquarium you’ve been dreaming of.
Understanding the Angelfish Personality: The Key to Harmony
Before we even start listing fish, we need to get inside the mind of an angelfish. They aren’t your typical, happy-go-lucky community fish. They are cichlids, and that comes with a certain attitude.
Angelfish are best described as semi-aggressive. This means they aren’t usually looking for a fight, but they won’t hesitate to establish a pecking order, defend their territory, or eat anything that can fit into their mouths. Think of them less as a peaceful neighbor and more as a stately monarch who demands respect.
Here are the key personality traits to keep in mind:
- They Get Big: A tiny, quarter-sized angelfish from the store can grow up to 6 inches long and 8-10 inches tall! That small mouth will get much bigger, making them a threat to small fish.
- Territorial Instincts: Especially as they mature and form breeding pairs, angelfish will carve out a section of the tank as their own and viciously defend it from intruders.
- Opportunistic Predators: If a fish is small enough to be seen as a snack (like a baby guppy or a small neon tetra), it will eventually become a snack. It’s not malice; it’s just nature.
Understanding these traits is the first and most crucial step in this angelfish care guide. It shifts your thinking from “what fish are pretty?” to “what fish are smart, safe choices?”
The Golden Rules: How to Choose What Fish Go Well With Angelfish
Now that you know what you’re dealing with, let’s establish some non-negotiable rules. Following these simple principles will save you a world of heartache and help you master how to what fish go well with angelfish successfully.
Rule #1: Size Matters (A Lot)
The number one rule is simple: do not choose fish that can fit in a full-grown angelfish’s mouth. This rules out many nano-fish like chili rasboras, celestial pearl danios, and, in many cases, even neon tetras (more on that later). Look for fish that are at least 2 inches long when fully grown.
Rule #2: Temperament is Everything
You need to find a balance. Avoid two types of fish:
- Fin Nippers: Fish like Tiger Barbs are notorious for nipping at the long, flowing fins of angelfish. This causes stress, injury, and opens the door to infection.
- Aggressive Bullies: Large, aggressive cichlids like Oscars or Jack Dempseys will bully and outcompete your angelfish, leading to a miserable existence for the angels.
You’re looking for fish that are peaceful but also robust and confident enough to not be intimidated.
Rule #3: Match the Water Parameters
This is a fundamental of fishkeeping that’s especially important here. Angelfish thrive in warmer water (78-84°F or 25-29°C) with a slightly acidic to neutral pH (6.5-7.5). Don’t try to force a fish that prefers cold, hard water (like many fancy goldfish) into an angelfish’s environment. It’s stressful and unfair to the fish.
Our Top 10 Best Tank Mates for Angelfish
Alright, let’s get to the fun part! Here is a curated list of fish that, in our experience at Aquifarm, have proven to be fantastic companions for angelfish. This is your go-to list for building a peaceful community.
1. Corydoras Catfish (Corys)
These adorable, armored catfish are the perfect bottom-dwelling janitors. They are peaceful, keep to themselves on the substrate, and are too wide-bodied for an angelfish to eat. They clean up leftover food and won’t bother your angels in the slightest. Don’t worry—these fish are perfect for beginners!
2. Bristlenose Pleco (Ancistrus sp.)
Forget the common pleco that grows to two feet long! The Bristlenose Pleco stays a manageable 4-5 inches, is a fantastic algae eater, and is heavily armored. They are nocturnal and will spend most of their time minding their own business on driftwood and glass, making them an ideal, low-maintenance tank mate.
3. Rummy Nose Tetras
If you want a schooling fish, Rummy Nose Tetras are one of the best choices. They are larger and faster than Neon Tetras, making them much less likely to become a meal. Their bright red noses are also a great “barometer” for water quality—if the noses are pale, it’s time to check your parameters!
4. Black Skirt Tetras (or GloFish Tetras)
These tetras have a deeper body shape that makes them unappealing as a snack. They are generally peaceful and hardy. Just be sure to keep them in a proper school of 6 or more to prevent any potential fin-nipping behavior, as a lonely tetra can sometimes get bored and mischievous.
5. Praecox Rainbowfish (Dwarf Neon Rainbowfish)
Rainbowfish are a fantastic choice. They are incredibly peaceful, fast-swimming, and occupy the upper levels of the tank, staying out of the angelfish’s way. The shimmering, iridescent colors of a school of Praecox Rainbows are a stunning contrast to the stately angelfish.
6. Harlequin Rasboras
A classic and reliable choice. Harlequin Rasboras have a triangular body shape that, like Black Skirt Tetras, makes them difficult for an angelfish to swallow. They are peaceful, active schoolers that add a wonderful dynamic to the mid-water level of the tank.
7. German Blue Rams
If you want another cichlid, German Blue Rams are a great option. They are a species of dwarf cichlid that stays small and peaceful. They share similar water parameter needs and will occupy the bottom to mid-levels of the tank. Be warned: they can be a bit sensitive to water quality, so they are best for a well-established aquarium.
8. Swordtails
These livebearers are large, active, and generally peaceful. Their size and speed make them a safe bet with angelfish. Opt for standard fin varieties, as long-finned “fancy” types can sometimes be targets for aggression. They add vibrant color and constant activity.
9. Platies
Similar to Swordtails but a bit smaller and chunkier, Platies are another excellent livebearer choice. They are hardy, peaceful, and come in a dazzling array of colors. Their robust body shape keeps them off the menu, and they are confident enough to coexist peacefully.
10. Kuhli Loaches
For something a little different, consider these eel-like bottom dwellers. Kuhli Loaches are shy, nocturnal, and fantastic scavengers. They will spend their time burrowing in the sand and weaving through decor, completely ignoring your angelfish (and being ignored in return).
Fish to AVOID: A Recipe for Disaster
Knowing what not to add is just as important. Adding the wrong fish can undo all your hard work. Here are the fish you should steer clear of, no matter how tempting they look at the store.
Fin-Nippers
These fish will relentlessly harass your angelfish, shredding their beautiful fins. The main culprits are Tiger Barbs and, to a lesser extent, Serpae Tetras. Just don’t do it.
Most “Nano” Fish
This includes Neon Tetras (yes, really!), Ember Tetras, Chili Rasboras, and Endler’s Livebearers. While some people have success with Neons if they are added before the angelfish are grown, it’s a huge gamble. To an adult angelfish, they look like little swimming snacks. It’s one of the most common problems with what fish go well with angelfish setups.
Aggressive or Large Cichlids
Never mix angelfish with large South or Central American cichlids like Oscars, Jack Dempseys, Green Terrors, or Convict Cichlids. They are far too aggressive and will bully your angelfish to death.
Fancy Guppies and Bettas
The long, flowing fins of fancy guppies and male bettas can trigger aggression in angelfish. Furthermore, a betta may see the angelfish as a rival, leading to constant stress for both parties. It’s a pairing that rarely works out in the long run.
Setting Up Your Tank for Success: Best Practices for a Peaceful Community
A successful community isn’t just about the fish; it’s about the environment you create. Following these what fish go well with angelfish best practices will dramatically increase your chances of success.
Tank Size is Crucial: A single angelfish or a pair needs a minimum of a 30-gallon tall tank. For a community with tank mates, a 55-gallon tank is the recommended starting point. The extra space reduces territorial disputes.
Go Vertical: Angelfish are tall. Use tall plants like Amazon Swords and Vallisneria, and tall pieces of driftwood. This caters to their natural shape and provides security.
Break the Line of Sight: A heavily planted tank with lots of driftwood and decor is essential. This allows fish to escape each other’s view, creating natural boundaries and hiding spots, which is key to diffusing aggression.
A Note on Sustainability: When building your community, consider a sustainable what fish go well with angelfish approach. Opt for captive-bred fish whenever possible, as they are hardier and reduce the impact on wild populations. Supporting aquacultured plants is another great way to create an eco-friendly what fish go well with angelfish aquarium.
Pro Tip: Add your angelfish to the tank last, especially if they are young adults. This allows the more peaceful “dither fish” (like tetras and rasboras) to establish themselves first, preventing the angelfish from immediately claiming the entire tank as their territory.
Frequently Asked Questions About What Fish Go Well With AngelfishCan angelfish live with guppies?
It’s highly discouraged. The flashy, long fins of male guppies are a magnet for fin-nipping from angelfish. Furthermore, guppy fry will be seen as a constant source of live food, and adult guppies are small enough to be at risk from a large angelfish.
What size tank do I need for angelfish and tank mates?
For a community tank that includes angelfish and other compatible fish, we strongly recommend a 55-gallon tank as the minimum. This provides adequate swimming space for everyone and helps minimize territorial behavior, which is a major benefit when keeping angelfish with other species.
Can I keep just one angelfish?
Absolutely! Keeping a single angelfish is often a great way to enjoy their beauty without dealing with the heightened aggression that comes from a breeding pair. A single “centerpiece” angelfish can be a wonderful addition to a community tank.
Should I add the angelfish first or last to the tank?
If you can, add the angelfish last. This allows the more peaceful schooling fish and bottom dwellers to settle in and claim their spaces. Adding angelfish to an already-established community makes them less likely to view the entire tank as their sole territory from the start.
Your Peaceful Angelfish Community Awaits
Choosing the right tank mates for your angelfish might seem daunting, but it all comes down to a few key principles: respect their size, understand their semi-aggressive nature, and build an environment where everyone has their own space.
By selecting robust, peaceful fish of a similar size and providing a well-structured aquarium, you’re not just avoiding conflict—you’re unlocking one of the greatest benefits of what fish go well with angelfish communities: a breathtakingly beautiful and dynamic aquatic ecosystem.
You now have the expert knowledge and the confidence to make it happen. Go forth, plan your perfect community, and enjoy the serene beauty of a well-balanced angelfish tank. Happy fishkeeping!
