[2][3] The species name, almiriensis, refers to Almiri, in the Peloponnese region of Greece where the fish was originally discovered.

[4] Like all members of the genus Aphanius, the fish display sexual dimorphism.

The dorsal fin is yellow and has a prominent black margin, with a few dark dots near the base.

Females bear 7–11 roundish blotches on their sides, connected by a dark midlateral stripe.

[3] Due to one of its home springs being dammed up with rocks in the late 1990s to early 2000s, and it being possibly extinct at its type locality, the IUCN considered the fish to be Critically Endangered on criteria B1ab (i, ii, iii, i, v) and B2ab (i, ii, iii, iv, v);[5] However, as it is now known to be much wider spread across the Mediterranean region, including the Aegean coast of Thrace, the Dodecanese Islands, Turkey and the heel of Italy, this has been revised to Least Concern.
