Guild Wars 2

Since we no longer are free to roam Lion’s Arch unhindered, is there any other location to find the armor fish pet? I think in the past, lion’s Arch was the only location of the tanky fish.

Apparently

Kryta
     Bloodtide Coast
     Sanguine Bay (Between Grand Barrier Isle and Dredgehat Isle)
Sea of Sorrows
     Sanguine Bay
     South of Barrier Camp Waypoint (Between Grand Barrier Isle and Dredgehat Isle)
Blazeridge Mountains
     Blazeridge Steppes
     Behem Gauntlet In a hidden series of caves behind the waterfall.
Steamspur Mountains
    Mount Maelstrom
    Whitland Flats South of Lonatl Grounds
The Mists
    Eternal Battlegrounds
    Water, east side of Green World Hill
