Tectonic Toadfish

Night and fog define the Tectonic Toadfish, a Rare fish listed for Obsidian Trench with Worm as the bait. The wiki pairs it with Autumn and Winter, and it is listed as obtainable.

Its weight runs from 1.2 kg to 4.5 kg, averaging 2.85 kg. The price is C$157.778 per kg, the average sale value is C$450 and the base XP is 435. That makes it 782nd of 1,059 documented fish by maximum weight and 558th of 1,038 by average value, so its price per kg does more for it than its size does.

Obsidian Trench documents 11 fish in total, and only one other shares the Rare rarity there, Cinder-Crust Gar. The wiki's description reads “A broad-headed bottom dweller that vibrates its swim bladder to create low-frequency rumbles echoing through seismic trenches.”

Verdict: a small, modestly priced Rare fish whose interest lies in belonging to a short zone list of 11 fish, with a single Rare neighbor.
