Biotoecus opercularis, or the fairy cichlid as it’s often referred to because of its very small size, is a South American species from Brazil. Maxing out at about 1.5 inches, this tiny cichlid is not very common in the hobby nor is it overly colorful. However, like many other dwarf species, its attraction is in its behavior, especially when spawning.

Reef to Rainforest just released a short piece about the species along with a fantastic video. Check it out!
