Angelfish Overview
Body Shape and Anatomy
Angelfish sport an interesting look due to their compressiform shape, which makes them slim from side to side. This nifty body design helps them slip through thick plants and tight spots that you’d find in their native hangouts. They’re not your usual torpedo or eel-shaped fish, which might be why they get a little extra attention in the aquatic world (University of Hawaii).
Environmental Requirements
These fish feel right at home in settings that echo the Amazon River in tropical South America, where they originate. They like peaceful, slow-flowing waters with a shadowy cover from vegetation or fallen branches above. A setup like this makes them act naturally and feel safe (Aqueon).
To keep them comfy in your aquarium, watch for these water settings:
- pH: Keep it between 6.8 and 7.8
- Hardness: Aim for 3° to 8° dKH (54 to 145 ppm)
- Temperature: Stay within 78° to 84° F
| Parameter | Ideal Range |
|---|---|
| pH | 6.8 – 7.8 |
| Hardness (dKH) | 3° – 8° (54 – 145 ppm) |
| Temperature | 78° – 84° F |
Staying on top of water changes is key—consider swapping out 10% of the water weekly or 25% every other week. Tools like the Aqueon Aquarium Water Changer or Siphon Vacuum Gravel Cleaner can make this job pretty straightforward.
These fish can grow quite a bit, so they’re going to need a tank that’s at least 55 gallons to stretch out when they’re fully grown. Tanks that are taller rather than wide work best, giving them room to swim about. Fill the tank with objects like broadleaf plants, vertical driftwood, and smooth gravel to make them feel right at home that mimics their natural digs (Aqueon).
While they’re usually calm, angelfish can get testy with one another, especially if they’re in the mood to spawn. They might pick on smaller fish too. Tank companions that usually get the green light include larger tetras, rasboras, gouramis, barbs, rainbowfish, corydoras, some catfish, and discus, provided it’s warm enough—over 82°F—in larger tanks.
Knowing how to keep their environment just right is essential for a happy and healthy life for your angelfish. Should you be craving more know-how on setting up an angelfish tank, head over to our angelfish aquariums guide.
Angelfish Diseases
When you’re raising angelfish, knowing about the different diseases they can catch is a must. The quicker you spot these trouble signs, the better your chances at keeping your angelfish healthy and happy.
Viral Infections
Angelfish are buddies with goldfish and koi in catching Viral Hemorrhagic Septicemia—a rough and super contagious disease. Sadly, there’s no magic cure. Watch out for:
- Bleeding under the skin
- Acting sluggish
- Bloated belly
Pulling infected fish from the tank and keeping water clean as a whistle are key to halting this virus. Need more intell on angelfish? Check out angelfish diseases.
Swim Bladder Issues
This pesky swim bladder problem loves to bug angelfish, especially the darker colored ones. It meddles with their ability to control swimming, showing symptoms like:
- Tilting to one side
- Bobbing upside down
- Struggling to swim
A bummer, but there’s no fix for this condition. Keeping water tip-top and feeding quality chow can lessen the impact and ease fishy stress (WetWebMedia). Want the scoop on fish moods? Head over to angelfish behavior.
Freshwater Velvet
Freshwater Velvet closes in on angelfish like unwanted guests, caused by tiny troublemakers Oödinium pillularis or Oödinium limneticum. They’re deadly, especially when fish are stressed or the water’s iffy. Signs of infection include:
- Fish looking like they’ve been dusted with gold
- Scratching on everything
- Gasping for air
To dodge this bullet, get serious about quarantining and keeping water as good as it gets (BunnyCart). For aquarium hacks, dive into angelfish aquarium.
Hole in the Head Disease
Hole in the Head disease isn’t only for Discus fish—angelfish get it too. The culprits? The protozoan Hexamita or a lack of necessary minerals. Look for:
- Decay on their head and along the lateral line
- White patches
- Going off their food
You can tackle this with API General Cure meds (BunnyCart). Head to angelfish diseases to learn more about what’s bugging your fish.
Fishkeepers might find quick disease-and-symptom charts handy.
| Disease | Cause | Symptoms | Treatment |
|---|---|---|---|
| Viral Hemorrhagic Septicemia | Virus | Bleeding, sluggish behavior, bloated belly | No cure, keep water clean |
| Swim Bladder Disease | Physical/Environmental stress | Tilted swimming, floating wrong | Pristine water, A+ diet |
| Freshwater Velvet | Oödinium pillularis | Gold dust look, scratchy fish, gulping air | Quarantine, check water quality |
| Hole in the Head Disease | Hexamita, mineral issues | Head sores, spots, lack of appetite | API General Cure meds |

Caring for Angelfish
Is there a fish that’s a bit like art in motion? Yep, that’s the angelfish for ya. Aquarium fans love these water wonders not just for their beauty, but also ’cause they’re pretty chill to care for. Before you welcome them into their new glass habitat, let’s chat about the essentials: keeping their water primo, giving them a snazzy tank to call home, and figuring out who they can hang out with.
Water Conditions
Imagine needing the right climate to bust a move. Angelfish are no different; they need just-so water to feel their best. They groove in warmer water with a pH between 6.8 and 7.8, and a water hardness of 3° to 8° dKH — that’s water chemistry for ya! Keep the water toasty, between 78°F and 84°F, so the little guys don’t get chilly.
Make your finned friends feel like rockstars by keeping their water spic and span:
| Parameter | Ideal Zone |
|---|---|
| pH | 6.8 – 7.8 |
| Hardness | 3° – 8° dKH |
| Temperature | 78°F – 84°F |
A once a week 10% water swap or 25% every other week will keep things fresh. Get the right gear, like the Aqueon Aquarium Water Changer or that Siphon Vacuum Gravel Cleaner to keep your tank clean as a whistle.
Tank Setup and Maintenance
Got angelfish? Think big! Your little swimmers can get quite a bit larger than you might expect, so give ’em at least a 55-gallon digs when they’re all grown up. They love to play up and down, so a tall tank is their jam.
Tank must-haves:
- Water that doesn’t feel like a raging river
- Big, leafy plants
- Wood placed standing up, like trees
- Smooth rocks on the bottom for them to nibble around
Keep it clean and pristine. Regular vacs and filter cleanings will keep funk away and prevent stuff like swim bladder disease.
Angelfish Behavior and Tank Mates
Yeah, angelfish are mostly peace-loving, until they get in the mood for love. Then they might pick a fight or go after smaller tank mates for a snack. Best buddies include:
- Bigger tetras
- Rasboras
- Gouramis
- Barbs
- Rainbowfish
- Corydoras
- Bigger cats
- Discus (when it’s 82°F plus and the tank is roomy) (Aqueon)
Steer clear of fish like goldfish—they’ve got different lifestyles and might not play nice together.

Breeding Angelfish
Spawning Behavior
Angelfish couples are known for getting cozy and dropping rows of eggs on whatever flat vertical surface they like, be it leaves, rocks, or even the aquarium glass. The mama fish kicks things off by laying the eggs, with papa fish trailing right behind to make sure everything’s fertilized. They’ll keep at it until they line up hundreds of eggs in neat little rows.
| Spawning Detail | Description |
|---|---|
| Preferred Surface | Leaves, rocks, aquarium glass |
| Number of Eggs | Hundreds |
| Egg Care | Parent cleaning before spawning |

Rearing Fry
Turns out, a lot of angelfish parents nowadays are lousy at the whole rearing thing and might even snack on their kids. So, what’s a responsible breeder to do? They trick the fish into laying their eggs on vertical surfaces and then whisk those surfaces away to a hatchery aquarium. Once the eggs are all laid out and fertilized, they’re moved separately to keep them safe from hungry parents.
Steps for Rearing Fry:
- Transfer Eggs: Get those eggs to a hatchery tank pronto!
- Monitor Eggs: Keep an eye out for fungus. A splash of methylene blue in the water helps prevent this.
- Fry Care: After hatching, the fry munch on their yolk sacs for a bit before looking for their next meal.
| Fry Care Detail | Description |
|---|---|
| Hatchery Aquarium | Separate tank away from parents |
| Initial Feeding | Yolk sacs |
| First Foods | Infusoria, freshly hatched brine shrimp |

Angelfish Care FAQs
Swim Bladder Disease
Swim bladder disease appears frequently in angelfish, especially those with a darker shade. This swim bladder organ assists in balancing their buoyancy, preventing them from awkwardly floating or sinking like a misguided submarine.
Look out for signs like sideways floating, tilting, or struggling with regular swimming. While full recovery from this ailment isn’t a guarantee, here are some strategies to make life a bit more bearable for your fish buddy:
- Maintain water conditions to keep stress levels low (angelfish temperature, pH, etc.).
- Offer a nutritious diet to fend off deficiencies.
- Use medication like Metronidazole or Nitrofurazone, if it’s suggested by an expert (WetWebMedia).
Bacterial Infections
Angelfish aren’t immune to bacterial bugs, which often manifest as odd lumpy growths. Whether these infections strike from within or attack the surface, each requires a different fix.
Internal infections might have your fish acting lethargic, turning up its nose at food, or showing visible lumps. The best bet? Treat Grandma’s little angelfish in a separate tank with meds like Metronidazole or Nitrofurazone. Always stick to the dosing instructions—you don’t want to overdo it.
External infections may leave behind ulcers or those dreaded red streaks. These benefit from similar treatment, along with ensuring the tank’s cleanliness to prevent stress or further infections.
Fish Integumentary System
The fish’s integumentary system, your angelfish’s outer armor, is key to wingman-level protection. Comprising the skin and scales, it boasts two main layers:
- Epidermis: This top layer makes mucus to ditch those pesky organisms during its underwater adventures.
- Dermis: The lower level’s got blood vessels, nerves, and some serious fiber-strength connective tissue (University of Hawaii).
Keeping a fish’s outer layer healthy involves:
- Ensuring sparkling clean water to stave off infections.
- Serving a healthy diet for glowing scales.
- Considering heat protectant treatments, if it feels necessary.

Angelfish Native Habitat
Getting angelfish comfy in your aquarium starts with knowing where they come from. These beauties hail from the freshwater zones of South America, especially the vast Amazon River. Let’s chat about their home turf and how you can make your tank feel like a slice of this paradise.
Amazon River System
Angelfish call a huge chunk of tropical South America home, especially in the Amazon. This massive river is like Disneyland for fish—offering everything an angelfish could ever dream of.
In the wild, angelfish hang out in:
- Calm, lazy waters.
- Shady spots with loads of plants for coverage.
The Amazon’s laid-back waters and lush greenery give them a safe haven and all the goodies they need (Aqueon).
Preferred Living Conditions
To make your tank feel like they’re back in the Amazon, you’ll want to mimic their preferred hangouts. Here’s what they love:
- Temperature: Keep things warm and cozy, between 76°F and 82°F. Check out our scoop on angelfish temperature for the full details.
- pH Level: They fancy slightly acidic to neutral waters, so aim for a pH between 6.5 and 7.5. Our angelfish pH level guide has got your back.
- Lighting: Soft lighting is their jam. Too much light feels like a disco, and they just want chill vibes.
- Aquarium Setup: Layer your tank with plants and provide some hideouts with overhanging greenery and driftwood for them to feel snug.
| Parameter | Sweet Spot |
|---|---|
| Water Temperature | 76°F – 82°F |
| pH Level | 6.5 – 7.5 |
| Lighting | Low to Moderate |
Setting up your angelfish aquarium means getting the water right, designing their planty digs, and picking the ideal companions for them. This keeps them happy, healthy, and less freaked out, which is key to a joyful tank life.
