How to catch Yellow Boxfish
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.

Coral Zone · Ostracion cubicus
The Yellow Boxfish has a perfectly boxy body covered in a thick layer of hard scales, deterring many predators from attempting a bite.
However, this heavy "armor" also leaves it powerless against even the gentlest of currents, making it clumsily "shuffle" around through the water.
