Fishtank Control
Your phone is the caretaker of a shared Fishtank aquarium. Scan the QR panel on the display to join its room.
Controls
-
Tank type: switch between Freshwater, Bioluminescent, Coral Reef, Jellyfish, Japanese Garden, Amazon Blackwater, Seahorse Garden and Rocky Cichlid using the selector at the top. Each type remembers its fish and scenery choices.
-
The fish: add or remove angelfish, discus, gouramis, neon tetras, guppies and corydoras using the plus and minus buttons. The bioluminescent category offers marine-inspired northern lampfish, dusky hatchetfish, black seadevils, twofin flashlightfish, Sloane's viperfish and Australian pineapplefish, with artistically enhanced neon colors and luminous fins. Scientific names and color palettes appear beside each species. Each aquarium holds up to 60 fish.
-
Feed the fish: release a serving of food and watch the fish follow it. Allow eight seconds between servings.
-
Coral Reef: choose clownfish, blue and yellow tangs, chromis, royal grammas and fire gobies. Coral Lagoon and Reef Arch provide white-sand aquascapes with swaying anemones, sea fans and soft corals.
-
The scenery: choose from the aquascapes in the selected category, change the lighting and water flow, or toggle the air bubbles. Show or hide the heading and QR panels independently.
-
Jellyfish: a near-black exhibit with moon, sea nettle, purple-striped, lagoon, crystal and flower hat jelly artwork. Translucent bells contract, long tentacles flex with a delayed wave, and a gentle current carries the jellies through the water. Choose Midnight Glass or Velvet Dusk; feed drifting plankton and adjust exhibit lighting. The default collection has 12 jellies. See artwork and generation prompts.
-
Japanese Garden: twelve koi-inspired fish in six colour varieties, including Kohaku, Sanke, Showa, golden, platinum butterfly and Tancho. Choose Stone Path or Moss Islands, with pale gravel, moss-covered stones, soft daylight, six swaying foreground plants and nine gently drifting maple leaves. Fish, feeding, lighting and scenery use the same shared controls. See artwork and prompts.
-
Amazon Blackwater: tea-coloured water, tangled roots and fallen leaves. Root Cathedral and Leaf Lagoon are 4K scenery designs with narrow warm shafts of light. Six fish species include silver dollars, silver hatchetfish, diamond tetras, rummy-nose tetras, black neon tetras and Sterbai corydoras. Each type retains its own population and scenery choices. See artwork and prompts.
-
Seahorse Garden: twelve upright seahorses in golden, peach, ivory, chestnut, sage and rose colour varieties. Curled tails hold onto swaying seagrass stems; the seahorses release, take frequent longer swimming trips in front of and behind the plants, turn beyond the screen edges, hover and settle onto new stems. Choose Seagrass Meadow or Willow Garden, both 4K JPEGs with pearl sand and branching ornaments. Feed small drifting morsels near their snouts. See artwork and prompts.
-
Rocky Cichlid: eighteen colourful fish in six varieties: electric yellow, cobalt zebra, red zebra, peacock, yellow-tail acei and frontosa. Choose Limestone Caves or Slate Terraces, both 3840 × 2160 JPEGs with pale sand and sculpted rock formations. Individually sized fish patrol local territories, inspect the rocks and retreat behind foreground shelters before emerging again. Four varied caves drift subtly with scenery changes. See artwork and prompts.
Several visitors can control the same tank together. Counts and selections update from the shared display, and return after the phone reconnects. Keep at least one aquarium display open. No name or account is required.
