What the name means

Leiodiscus atramentaria means roughly “inky smooth-disc”: from leio- (smooth) and discus (disc), and atramentaria (inky). Every species name is built from its genes: the dorsal fin and body plan give the genus, the colouring gives the species name, and the tail and mouth the last word.

How to find one

Dive to the abyss (it opens at diving level 18) and look for a deep with Abyss Ink colouring, or breed for it: you need all five of its traits to show at once, and some of them may be recessive, hidden in a parent’s second gene copy. The breeding screen shows the exact odds. See how fish genetics work.
