Electric Blue Acara

A shimmering blue cichlid that is remarkably tolerant for its family — one of the few mid-sized cichlids that can live alongside calm schooling fish. Pair-bonded and easy to keep.

• Minimum footprint: 30 gallons; a 40+ gallon tank gives real swimming room.
• Preferred swimming zone: middle of the water column.
• Social — keep a group of at least 2.
• Care level: easy.

• Temperature: 72–82°F
• pH: 6.5–7.5
• Hardness: 3–15 dGH (Moderate)

Stable parameters matter more than perfect ones — aim for consistency before chasing an exact number.

An omnivore — offer a staple flake or pellet plus regular frozen or live foods (daphnia, bloodworm, brine shrimp) and some vegetable matter for balance.

Standard tanks at or above the recommended 40 gallons:

• 40 gallon Breeder 36 × 18 × 16″
• 40 gallon Long 48 × 12 × 16″
• 55 gallon 48 × 13 × 21″
• All tank sizes

• Start from a 30 gallon minimum and plan the full group size (2+) before you buy.
• Activity level is moderate, which affects how much of the tank it uses and how much it adds to the bioload.
• Zoning matters: this species lives mostly in the middle zone, so choose tank mates that occupy other levels.

Compatibility depends on tank size, water chemistry, temperament, and adult size. Run a full check against any species in our database.
