overview
who is the midas cichlid
Cichlid from the San Juan River basin in Nicaragua and Costa Rica, including Lakes Nicaragua (Cocibolca) and Managua (Xolotlán), and crater lagoons such as Masaya and Apoyo. It lives on rocky shores, with crevices where it spawns and guards its young, and is uncommon in rivers. It eats algae and what grows on the rocks, snails, larvae and small fish. About one in ten changes color as it grows and turns orange or gold; the rest are gray, brown or black, camouflaged on the bottom. It is the basis of one of the most studied cases of speciation in fishes. For anglers it is a light, fun target, caught with natural bait or micro-lures.
fun facts
- In Nicaragua's crater lagoons, populations of the midas cichlid complex gave rise to new species, a classic case of sympatric speciation.
- The orange form, rare in nature, was the most sought after by the aquarium trade.
how to recognize it
identification
Deep, compressed body, small mouth with thin lips; adult males develop a bump on the nape and longer fins. Two color patterns: gray to brown with dark bars, or orange to gold, sometimes with black spots. The red devil (Amphilophus labiatus) has thick lips and a more pointed snout; tilapias have a different mouth and a dark spot on the dorsal fin of juveniles.
