Assorted Oscar

Care requirements

• Minimum tank 60 × 24 in (150 × 60 cm) or larger.
• Adult size 14 in (350 mm), excluding the tail
• Temperature 75–79°F (24–26°C)
• pH 6.5–7.5
• GH 5–12 dGH
• Ammonia and nitrite 0 ppm

Housing & compatibility

Plan around the full adult size. Use a large, well-filtered aquarium with a secure lid and keep small fish out of reach. Territorial fish may need separate housing.

Diet

Use a complete large-cichlid pellet as the staple. Offer suitable frozen or prepared foods for variety. Remove any leftovers.

Hikari Sinking Cichlid Gold works if the formula and size fit.

Species notes

Oscars (Astronotus ocellatus) are large cichlids with heavy appetites and a high waste load.
