Broken Scylla

Broken Scylla is the most extreme weight entry you will find among these fish. Tagged as an Admin Event catch under the name Glitchstorm, this Special fish ranges from 20,000,000 kg to 105,000,000 kg, averaging 35,000,000 kg. Its maximum weight ranks 2nd of the 663 fish with a documented weight.

The weight is where the value comes from, since the rate is only C$0.003 per kg. Even so, the average sale reaches C$115,797.5, which is 24th of the 742 documented fish. The base XP is only 248, so unlike many top-value fish it is not an XP prize. The wiki lists no bait, weather, season or time of day, and no rod or fish of the same tier is attached to it.

That absence of requirements is the whole point: the entry is about being present for the event, not about preparing a setup. If a Glitchstorm happens while you are fishing, this is a once-in-a-while chance to land something worth over C$100,000.

Practical advice: if one comes up, sell it. The XP will not move your level much, and the C$ payout is among the highest of any documented fish. Do not plan around it, because the event is not something you can trigger.
