How to catch Blackfin Pearlfish
Use the Fishing Rod. The exact approach depends on the creature’s category and, for shore-dwellers, its species type.
- Cast the Fishing Rod into the right water: rivers and lakes for freshwater fish, coastal waters for saltwater fish.
- Wait for the nibbles, then strike when the line bites down.
- Higher-quality saltwater fish need a slow reel-in. Keep the line from snapping instead of holding the button down.
First catch: the creature is added to the Omnidex. Offer it to Mors at the Omni-Gallery to put it on display and unlock its Omnipedia entry.

The blackfin pearlfish aren't particularly difficult to breed in captivity.
Once the "nursery" has been set up with peat soil and shelters with hiding spots are added, a mature pair of blackfin pearlfish will soon begin their breeding process. The eggs, buried in the peat soil, can survive out of water in a dry state for a reasonably long time.
While the blackfin pearlfish have relatively short natural lifespans, this unique breeding strategy is their way of ensuring survival of the fittest.
