Cichlasoma sp.

Size Range & Growth Potential

• Cichlasoma as a genus typically includes medium-sized South American cichlids; examples like the Black Acara (Cichlasoma bimaculatum) average around 10 cm, reaching up to 15 cm in good conditions 

• Other species such as C. portalegrense can grow to 20–25 cm 

• Hybrid "parrot" variants (e.g., from pet trade) may reach 10–15 cm (4–6 inches) 

Care Overview (Juvenile 2.5–3 cm)

Here’s a polished, link-free breakdown of care essentials suitable for juveniles in this size range:

Tank & Environment

• Minimum Tank Size: Start with 75 liters (20 gallons) for growing juveniles; increase to 150 liters (40+) for adults due to space and territory needs.

• Provide rocks, driftwood, and hiding spots to support natural exploration and territory establishment.

• Include robust plants (attached to décor) as many Cichlasoma species may dig.

Water Conditions

• Temperature: 24–28 °C (75–82 °F)

• pH: Neutral to slightly alkaline (~6.5–7.5)

• Hardness: Moderate (approx. 8–20 dGH)

Diet

• Omnivorous—offer a varied diet of quality pellets/flakes augmented with live or frozen foods (e.g., brine shrimp, bloodworms) for growth and color.

Behavior & Social Setup

• Generally semi-aggressive and territorial, especially during breeding.

• Best housed with other robust, similarly sized species to avoid undue stress or predation.

Breeding (General Cichlid Behavior)

• Many species are substrate spawners; parents may guard eggs and fry.

• Provide flat stones or smooth surfaces for spawning. Parental care varies—some species are cooperative.

Lifespan & Adult Size

• Most reach 10–25 cm (depending on species or hybrid variant), with juveniles (2.5–3 cm) growing rapidly into full adult size.

• Lifespan often falls in the 5–10 year range under optimal conditions.
