Angelfish care guide

Angelfish tank size

Plan for a tank length of at least 90 cm for an angelfish. Seriously Fish recommends a 100 cm tank base, which provides extra physical space for swimming and accommodating aquatic plants alongside growing adults.Plan for a tank length of at least 35 in for an angelfish. Seriously Fish recommends a about 3 ft (39 in) tank base, which provides extra physical space for swimming and accommodating aquatic plants alongside growing adults.^[1]

Vertical room is just as critical as length. Provide a tank height of 50 cm, as recommended by Seriously Fish for adults, because their long dorsal and anal fins need vertical clearance beyond basic horizontal swimming margins.Vertical room is just as critical as length.

Angelfish water parameters

Keep your water temperature stable within 24–30 °C, picking a consistent point that also matches any shared inhabitants. Maintain a practical pH range of 6.0–7.4 and a general hardness within 1–15 dGH.Keep your water temperature stable within 75–86 °F, picking a consistent point that also matches any shared inhabitants. Maintain a practical pH range of 6.0–7.4 and a general hardness within 1–15 dGH.^[1]

Fully establish your biological filter before introducing angelfish to the aquarium. Adult cichlids produce significantly more metabolic waste than small juveniles, so monitor ammonia and nitrite concentrations closely after adding new stock or increasing daily feeding amounts.Fully establish your biological filter before introducing angelfish to the aquarium.

Feeding angelfish

Feed your angelfish twice daily, offering an amount they consume within about two minutes. Provide quality tropical flakes or sinking pellets as a daily base, and rotate thawed bloodworm, daphnia, or brine shrimp into the schedule for variety.Feed your angelfish twice daily, offering an amount they consume within about two minutes.

Keep meal sizes modest even if your angelfish rushes to the front glass every time you approach. An eager feeding response indicates normal curiosity, but a fish's willingness to eat does not reveal its actual nutritional requirement.Keep meal sizes modest even if your angelfish rushes to the front glass every time you approach.

Angelfish behaviour

Expect a typical adult length around 12 cm, with larger specimens reaching 15.2 cm. Deep body profiles and extended vertical fins make these cichlids far more substantial in physical presence than their base horizontal length suggests.Expect a typical adult length around 5 in, with larger specimens reaching 6 in. Deep body profiles and extended vertical fins make these cichlids far more substantial in physical presence than their base horizontal length suggests.^[1]

Watch your group closely as individuals mature and form pairs. Fish that coexisted calmly as juveniles often begin defending territory aggressively once breeding begins. Plan on a five to ten year lifespan, though some healthy fish survive longer.Watch your group closely as individuals mature and form pairs.

Breeding angelfish

Angelfish deposit their eggs onto clean upright surfaces, including broad plant leaves, flat slate pieces, or the aquarium glass. A bonded pair thoroughly cleans their selected site, guards the clutch, and protects the hatched wrigglers.Angelfish deposit their eggs onto clean upright surfaces, including broad plant leaves, flat slate pieces, or the aquarium glass.

Prepare fry foods before the young absorb their yolk reserves and become free-swimming. Offer newly hatched brine shrimp once they start swimming actively, followed by appropriately sized micro fry foods as the brood matures.Prepare fry foods before the young absorb their yolk reserves and become free-swimming.

Angelfish health problems

Ich produces visible small white spots over the skin and fins, accompanied by gravel rubbing or laboured breathing. This external parasite frequently enters displays on new arrivals showing no visible outward signs, so quarantine all fish for 30 days and never share unsterilised nets or equipment.Ich produces visible small white spots over the skin and fins, accompanied by gravel rubbing or laboured breathing.

Fin rot causes ragged, eroding fin margins that may exhibit bloody red streaks. Physical trauma from aggressive tank mates and dirty water invite opportunistic bacterial infections. Remove persistent fin-nipping companions, run water tests, and correct lapsed maintenance routines.Fin rot causes ragged, eroding fin margins that may exhibit bloody red streaks.

Pop-eye causes one or both eyes to protrude unnaturally from the eye socket. Underlying causes range from internal bacterial infections to poor water quality. Inspect ammonia, nitrite, and nitrate levels immediately, observe the fish for concurrent symptoms, and reduce stress through clean conditions.Pop-eye causes one or both eyes to protrude unnaturally from the eye socket.

Male or female?

Do not depend on body size or forehead profile to sex angelfish reliably. Physical differences remain ambiguous outside active spawning windows. When a pair deposits eggs, examine the visible genital papilla: the male displays a noticeably smaller, more pointed organ than the female.Do not depend on body size or forehead profile to sex angelfish reliably.
