A moody deep-sea aquarium you check in on
Deep Sea Tank takes the same calm aquarium care loop as the rest of AnonArcade's virtual pet games and gives it a darker, deep-ocean cast: a drifting jellyfish, a curious octopus, a squid, and a shark, each with its own hunger bar. Tap any resident directly to feed it, or tap Clean Tank to refresh the shared water. This is a care game, not a survival one, so the shark never threatens its tank mates.
Needs drift down slowly over real elapsed time rather than only while the page is open, so a quick daily check-in is enough to keep the whole tank comfortable. Nothing here can die, get sick, or disappear, hunger and water cleanliness can drop as low as 0, but a little feeding and cleaning brings everything right back.
A daily streak counts consecutive check-ins. Like every game on AnonArcade, it's free with no download, no account, and nothing saved anywhere but your own browser. See more animal-themed games on the Virtual Pet Games page.
Frequently asked questions
How do I play Deep Sea Tank?
Tap any creature to feed it, and tap Clean Tank to refresh the shared water. Each creature has its own hunger bar.
Is a shark safe to keep with the other creatures?
Yes, this is a calm care game, not a survival simulation, so nothing ever attacks or harms anything else in the tank.
Can anything in the tank die?
No. Needs can drop to 0 but nothing ever dies or disappears. Feed and clean whenever you're ready to bring things back up.
