Quality and star rating both affect the sale price. MAX-size catches have a glowing aura.

Use the Fishing Rod. The exact approach depends on the creature’s category and, for shore-dwellers, its species type.

  1. Cast the Fishing Rod into the right water: rivers and lakes for freshwater fish, coastal waters for saltwater fish.
  2. Wait for the nibbles, then strike when the line bites down.
  3. 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.

Habitat: Mountain Lake. Distribution: All Regions.

Season: Year-Round. Time: Nighttime. Weather: Rainy. If two of those tags are restrictive, check the creature tracker before you set out.

The scientific name of the Red-Spotted Loach generalizes its "beauty," which does little to make the fish marketable to the public. Thus, it was given a catchier trade name among aquarists — the "red diamond loach."

The good news is that, despite its fancy new title, its "cost of living" hasn't skyrocketed accordingly.
