What the name means
Diplochaetodon ferruginea means roughly “rust-coloured double-bristle-tooth”: from diplo- (double) and chaetodon (bristle-tooth), and ferruginea (rust-coloured). 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 under the ice (it opens at diving level 1) and look for a butterfly with Rust Vent 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.
