How to catch Sweetfish
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.
- Common freshwater fish and gray saltwater fish can usually be caught straight away after the bite.
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.

Sweetfish have a strong sense of territory and usually stay within their claimed areas.
Therefore, a unique "decoy fishing" method is used for sweetfish — using one sweetfish as bait in another sweetfish's territory will lure out the resident, making it easier to catch.
