What the name means
Histiodiscus algarum means roughly “of the kelp sail-disc”: from histio- (sail) and discus (disc), and algarum (of the kelp). 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 midnight water (it opens at diving level 10) and look for a deep with Kelp Ghost 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.
