What Tank Size is Best for Angelfish?

Angelfish are not small fish – they grow tall and wide, so they need space to swim freely.If you’re keeping just one or a pair, go for at least a 70- liter tank. If you want to keep a group, 113 - 151 liters is a better choice.

What is the Right Water Temperature and Conditions?

Angelfish love warm, clean water.

• Temperature: 25°C to 28°C (77°F to 82°F)

• pH: Between 6.5 to 7.5

• Water hardness: Soft to moderately hard

Install a heater and use a thermometer to keep track of the water temperature daily.

Do Angelfish Need a Filter?

Yes! A good filter keeps the water clean and removes harmful waste. Angelfish do best in low-flow filters – strong current can stress them.

Use a sponge filter or hang-on-back filter, and clean the filter media once in 2–3 weeks.

What Do Angelfish Eat?

Angelfish are omnivores, which means they eat both plant and animal-based food.

Feed them:

• High-quality flakes or pellets

• Frozen or live foods like bloodworms, brine shrimp

• Blanched spinach or peas (once in a while)

Feed 2 times a day and give only what they can finish in 2-3 minutes. Overfeeding = bad water = unhappy fish!

Do Angelfish Like Plants?

Yes! Angelfish enjoy swimming through tall plants like Amazon swords, Vallisneria, and Anubias. Plants give them hiding spots and make them feel safe.

Angelfish are mostly peaceful, but they don’t like fin-nippers or aggressive fish.

Best tank mates:

• Corydoras

• Mollies

• Platies

• Gouramis (peaceful ones)

• Ram cichlids

🚫 Avoid keeping them with bettas or tiger barbs.
