Cichlids


Cichlids are freshwater fish known for their diverse body shapes, colors, and personalities. They can be aggressive or peaceful, and range in size from small to large.

𝑀𝑒𝑠𝑜𝑛𝑎𝑢𝑡𝑎 (flag cichlids) comprises six described species, but several putative new species are also known and have made their way into the aquarium hobby. The authors of this study use a DNA-barcode technique to (1) delimit species within 𝑀𝑒𝑠𝑜𝑛𝑎𝑢𝑡𝑎, (2) to test the 𝑀. 𝑖𝑛𝑠𝑖𝑔𝑛𝑖𝑠 species complex, and (3) go on to discuss the distribution of 𝑀𝑒𝑠𝑜𝑛𝑎𝑢𝑡𝑎 species with fascinating results.
