Flag Acara (Smiling Cichlid)
Laetacara curviceps
The *Laetacara curviceps* (commonly known as Flag Acara or Smiling Cichlid) is the forgotten jewel of fishkeeping. Often ignored because of its dull juvenile coloration, this small Acara transforms into a breathtaking, stocky and robust adult fish, exhibiting a deep turquoise/teal body, dotted with silver, a firm black line along the eye and fins bordered in bright red. Less chemically demanding than Rams and decidedly less aggressive than Apistogramma, the Curviceps combines fantastic rusticity with an adorable temperament, being perhaps the calmest and most peaceful cichlid that can be housed in an 80 cm (30-inch) community aquarium.
