Amatitlania siquia is a species of cichlid native to Central America.

[2][3] These cichlid can be identified by black melanin-based stripes in males and an additional bright orange spot on the abdomen for females.

Darker stripes in males and smaller spots in females are characteristic of more proactive Amatitlania siquia.

[4] Males of this species have been shown to exhibit alternative reproductive tactics (ARTs) by making their physical appearance similar to those of females.

[5] In 2019, scientists have shown that members of this monogamous species of fish develop a pessimist attitude when their partner is absent.
