Fish Tank: every item in the shop

Tanks

You start with a small tank with room for 4 fish. Each size up is bought once and keeps everything in it.

Medium tank

level 2 · 60 shells · room for 8 fish

Moves your fish into a bigger tank. More water means a full tank clouds over no faster than a small one, so the one you saved up for is calmer to keep, not more work.

Large tank

level 4 · 180 shells · room for 14 fish

Moves your fish into a bigger tank. More water means a full tank clouds over no faster than a small one, so the one you saved up for is calmer to keep, not more work.

Grand tank

level 7 · 450 shells · room for 22 fish

Moves your fish into a bigger tank. More water means a full tank clouds over no faster than a small one, so the one you saved up for is calmer to keep, not more work.

A second tank

One tank of each water. The two share a wallet and a level; everything else is their own.

Saltwater tank

level 4 · 150 shells · once

A saltwater tank beside your freshwater one, with clownfish, royal grammas, firefish, a blue tang and the lionfish, and a line-up to pick its first fish from. Set a Tank key to Saltwater to open it.

Freshwater tank

level 1 · 60 shells · once

Only if your first tank is saltwater (it could be converted before 1.2): a freshwater tank to go beside it.

Lights

The basic hood comes with the tank. A brighter light shows the colours off and grows the plants and coral that need it, but algae grows faster under it too.

Planted light

level 3 · 70 shells · algae 15% faster

Lets live plants grow. Needed before the shop will sell you any.

Reef light

level 5 · 180 shells · algae 30% faster

Bright enough for coral and anemones in a saltwater tank, and it makes every fish glow.

Food

Everyone starts on flakes. Better food is bought once and used from then on: it fills a fish further, pleases it a little, and leaves less behind to rot.

Sinking pellets

level 2 · 45 shells · fills 33% more, 15% less mess, +2% happiness

Pellets sink to the bottom, so the slow fish and the bottom feeders get their share.

Frozen brine shrimp

level 5 · 120 shells · fills 73% more, 30% less mess, +5% happiness

A treat they go wild for, and the best for bringing a pair into breeding condition.

Plants and decor

Everything you put in the tank makes the fish a little happier, and some of it keeps the water cleaner. Decor and food together add at most +15% happiness, and however planted a tank is, it still needs cleaning.

Plastic plant

level 1 · 12 shells · up to 6 · +2% happiness, water dirties 2% slower

A cheap way to make the tank feel lived in. Fish like having something to swim round.

Live plant

level 3 · 30 shells · up to 6 · +5% happiness, water dirties 8% slower

Real plants take up some of the waste, so the water stays clear for longer. They need the planted light to grow.

Rock pile

level 2 · 10 shells · up to 3 · +2% happiness

A little pile of stones for the fish to explore.

Moss ball

level 2 · 18 shells · up to 4 · +2% happiness, water dirties 3% slower

Soft green balls that roll about the sand and soak up a little of the dirt.

Driftwood

level 3 · 50 shells · up to 2 · +4% happiness

A gnarled branch of driftwood, a favourite hiding place.

Dragon stone

level 3 · 55 shells · up to 2 · +4% happiness

Craggy, rust-coloured stone that makes a tank look like a scape.

Lava rock

level 4 · 45 shells · up to 3 · +3% happiness, water dirties 2% slower

Porous rock that holds on to a little of the dirt.

Seiryu stone

level 5 · 80 shells · up to 2 · +5% happiness

Pale blue-grey stone with sharp ridges, the classic aquascaping rock.

Quartz cluster

level 6 · 95 shells · up to 2 · +5% happiness

A cluster of crystals that catches the light.

Bubbling chest

level 3 · 40 shells · up to 1 · +4% happiness

A treasure chest that bubbles now and then. One per tank.

Castle

level 5 · 90 shells · up to 1 · +5% happiness

The centrepiece every tank deserves. One per tank.

Saltwater decor

Sold in the saltwater tank's shop.

Live rock

level 1 · 45 shells · up to 3 · +4% happiness, water dirties 5% slower

Rock alive with the bacteria that keep a reef clean. The saltwater answer to live plants.

Coral

level 2 · 60 shells · up to 3 · +6% happiness

Colour for a reef tank, and the fish love it. Needs the reef light.

Wavemaker

level 3 · 55 shells · up to 1 · +5% happiness, water dirties 4% slower

Keeps the water moving, which marine fish enjoy and which carries dirt away. One per tank.

Anemone

level 4 · 85 shells · up to 2 · +6% happiness

Swaying tentacles for your clownfish to call home. Needs the reef light.

Breeding box

level 2 · 35 shells · one per tank

Eggs laid inside are safe from hungry fish, and it doubles as a hospital: a fish with white spot can be kept apart in it so it doesn't spread.

The clean-up crew

Shrimp and snails graze algae off the glass and pick up leftovers. They never go hungry while there is a film on the glass, but water left filthy sees them off. A hungry lionfish will eat a shrimp.
