Fishing in High on Life 2 is a collectible side activity that feeds directly into the Quarters Aquarium — a tank inside your base that tracks every unique fish and item you've pulled from the water. There are eight fishing spots spread across PinkLine Harbor, Circuit Arcadia, and the Zoo, and clearing all of them is required to unlock the Tanks For The Memories objective. The total collection sits at 35 unique catches, and each spot holds fish you won't find anywhere else.
Quick answer: You need the Fishing Rod from PinkLine Harbor's Beach Area (unlocked after getting Travis as a gun), then visit all eight fishing spots — three at PinkLine Harbor, two in Circuit Arcadia, and three at the Zoo — to collect every fish and item for the Quarters Aquarium.

How to get the Fishing Rod
The Fishing Rod becomes available once you unlock Travis as a usable gun during the main story. Head to PinkLine Harbor's Beach Area and find the NPC standing on the shore near a sunken boat. He'll ask you to raise his boat, and once you do, he hands over the rod — which the game calls Rod. You keep it permanently, and the first fishing spot is right there on the same stretch of beach.

Reel mechanics and catching fish
Fishing isn't a simple cast-and-wait affair. You need to tap the reel button in specific rhythms to get a fish to bite, and the pattern changes depending on the species. Some fish respond to slow, deliberate taps. Others want quick double taps. A few require three taps, a brief pause, then three more taps. If a fish isn't biting, switch up your rhythm until something connects.
Once a fish is hooked, you'll need to reel it in by keeping it inside an inner circle on screen. Move in the opposite direction the fish is pulling to maintain control. This takes some practice, especially on the trickier catches later in the game.

Fishing Spot 1 — Beach (PinkLine Harbor)
This is where you pick up the rod, so it's naturally the first place you'll fish. The water is calm with no environmental hazards, making it the ideal location to experiment with different tap rhythms and get comfortable with the reeling mechanic before moving on to trickier spots.
Fishing Spot 2 — Little Island (near the Beach)
A small patch of land sits just off the shore, surrounded by water. You'll need to skate across to reach it. Once you're standing on the island, cast your line outward into the surrounding water. The tight positioning can make your angle feel off, so adjust where you're standing until the cast lands cleanly.

Fishing Spot 3 — Pier Under the Cruise Ship
Tucked beneath the large cruise ship structure at PinkLine Harbor, this spot is one of the most commonly missed locations in the game. Players tend to search on top of the pier rather than underneath it. Look below the dock area and you'll find the fishing point. Many people end up discovering this one last, after they've already cleared every other spot on the map.
Fishing Spot 4 — Riverside, Circuit Arcadia
This location opens up as you progress through the main story and reach Circuit Arcadia. The complication here is a riverboat that periodically passes through the area. If it rolls by while you're casting, it can disrupt your line. Wait for the boat to clear before throwing, and time your casts between its passes to avoid wasted attempts.

Fishing Spot 5 — Near Ria Pharmaceuticals, Circuit Arcadia
At the bottom of the staircase near Ria Pharmaceuticals, you'll find a straightforward casting area with no environmental interference. The water is stable, and the positioning is clean, making this one of the easier spots in the game. It's a good place to mop up any remaining fish from the Circuit Arcadia region.
Fishing Spot 6 — Zoo (center of the map)
Positioned near the middle of the Zoo area, this spot is convenient if you're already rotating between objectives in the region. It isn't particularly challenging, but it holds mid-to-late game catches that are important for filling out the aquarium. Worth stopping by whenever you're passing through.

Fishing Spot 7 — Near the Skate Bowl
Located beside the Skate Bowl, this spot has uneven terrain that can make casting feel awkward. If your line keeps landing in the wrong place, reposition yourself along the edge until you find a cleaner angle. Once you're properly aligned, it functions like any other fishing location.
Fishing Spot 8 — Big Zoo Aquarium
The final fishing spot is inside the large aquarium structure within the Zoo. This tends to be one of the last locations players clear when wrapping up their collection. It's also tied to other collectibles in the area — notably, the third Ball Guy needed for the Ball Gun can be found here as well. Explore the full aquarium thoroughly before moving on.

Completing the Quarters Aquarium
| Region | Fishing Spots | Notes |
|---|---|---|
| PinkLine Harbor | Beach, Little Island, Pier Under the Cruise Ship | All accessible early; pier spot is easy to miss |
| Circuit Arcadia | Riverside, Near Ria Pharmaceuticals | Riverside requires story progress; watch for the riverboat |
| Zoo | Center of map, Near Skate Bowl, Big Zoo Aquarium | Big Zoo Aquarium also has the third Ball Guy |
Once you've pulled every unique fish and item from all eight spots, the Quarters Aquarium fills up, and Tanks For The Memories becomes available. There's no special order you need to follow — just make sure you've visited every location and caught all the golden-sparkle fish at each one. If your aquarium count is stuck, revisit the pier under the cruise ship first, since that's the spot most players overlook.
