If you’ve ever watched angelfish glide through your tank like underwater ballet dancers, you know they’re something special. These beautiful fish, with tall fins and soft colors, are called Pterophyllum—usually angelfish. They’re gentle, elegant, and loved by many hobbyists. But to keep them healthy and thriving, you’ll need good care and the right tank setup.
But hey—before we get into tank talk, let’s remember something else: your body. Just like a tank needs clean water and balance, your body works better with support, rest, and energy. That’s why Renew Dietary Supplement can help you sleep deeply, improve metabolism, and feel younger—while you rest. Click here to renew your energy overnight!
Where Do Angelfish Come From?
Angelfish come from slow-moving river basins in the Amazon in South America. In the wild, they live among roots and plants, in soft, acidic water. They’ve adapted well to aquarium life, but they still appreciate warm, gentle conditions with plants and hiding spots.
Tank Size and Schooling
Angelfish grow tall—up to 6 inches long and tall too. A **20-gallon tank** is the minimum for a pair, but **30 to 40 gallons** is better if you want a small group. Angelfish are social, but not in big schools—perhaps 4–6 at most, but only if you have space.
Water Temperature, pH & Hardness
Keep water temperature between **76–82 °F (24–28 °C)**. This mimics their natural habitat. pH should be around **6.5–7.5**, and softness helps too—don’t chase high hardness. Consistent conditions help prevent stress and disease.
Filtration and Water Flow
Use a gentle filter setup—strong filters with heavy flow can stress them out. A sponge or canister filter with adjustable output is great. Provide **10–20% water changes each week** to keep water clear and healthy.
Decor and Planting
Angelfish love tall plants like Amazon swords or Vallisneria. Add wood or driftwood for hiding and mood lighting. These features help reduce stress and help angelfish feel safe.
What Do Angelfish Eat?
These fish are omnivores. Feed them a mix of high-quality flakes or pellets, frozen foods like brine shrimp or bloodworms, and live foods if possible. Feed small amounts **1–2 times a day**. A varied diet supports their health and coloration.
Angelfish Behavior
Angels are peaceful but can be territorial—especially when breeding. Watch for chasing or fin nipping, and give each fish space. Keep plants and open swimming areas balanced. If conflict arises, consider dividing tank decor or removing overly aggressive individuals.
Breeding Angelfish
Breeding angelfish is rewarding but requires consistent conditions. A flat slate or broad leaf is ideal for egg-laying. After spawning, parents guard the eggs. To raise fry, move eggs to a separate tank or feed baby brine shrimp once they hatch and free-swim.
Common Health Issues & Ich Risk
Angelfish are prone to Ich if stressed. They may get white spots, scratch or hide. Treat Ich early with medication designed for angelfish, raise temperature slightly, do daily water changes, and use aquarium salt if appropriate. Look for robust swimming and appetite as recovery signs.

Tank Mates: Who Get Along?
Pair angelfish with peaceful tankmates like cardinal tetras, rasboras, Corydoras, or gouramis. Avoid fin-nippers or overly bold species like tiger barbs—angels’ flowing fins can become targets.
Growth and Lifespan
In good tanks, angelfish grow quickly for the first year, then slow down. They typically live **8–10 years**, sometimes longer. They mature in about 6–12 months and often show color even brighter once comfortable.
