Review summary

Reviewers consistently praise Jellyfish Aquarium as a relaxing, visually pleasing idle pet game with soothing music and a calm underwater vibe. The simple upkeep and long-term progression appeal to many, who form attachments to their jellyfish over days or years. Common downsides include the emotional impact of jellyfish death, limited customization options, and potential tedium for long-term play. There are also occasional alarming notifications about hunger or death. Overall, it’s a peaceful, low-stress experience with minimalistic charm that resonates with fans of serene pet sims.

Pros

Calming, anti-stress experience with soothing music and ambient lighting
Beautiful visuals with a deep ocean vibe and customizable lighting options
Simple, easy-to-care-for gameplay that stays away from complicated systems
Strong long-term engagement and attachment potential, with jellyfish thriving over many days/years
Minimalist design and peaceful pace that serves as a relaxing wind-down app

Cons

Jellyfish deaths can be emotionally distressing for players, as the pet often dies in the game
Limited customization or interaction (cannot name the jellyfish and tank decoration is minimal)
Some players find the gameplay repetitive or boring after extended play sessions
Occasionally unsettling or inaccurate notifications about hunger or death can be jarring

2026-06-12	me*****	I miss my jellyfish so much. It was 163 days, and i spent less time on my phone and forgot to feed and clean the tank. I wish there was an option to go back, or have any option to look at them one more time.

2026-06-01	Mi*****	Honestly the game is great! The music is beautiful, the art is amazing, and the jellyfish are adorable. I do have a few suggestions though. If they die, I think there should be a page on screen where it shows how long they lived along with how their health was. And when the jellyfish gets too big for its tank, you should be able to zoom the screen out to make the tank bigger

2026-03-29	El*****	Hi, I love this app so much I have a loyal jellyfish named coyote Peterson. He is 285 days old now and I am really starting to worry he is getting really big and having a hard time moving around. I am wondering if he will eventually be able to have a bigger tank because I can tell that he’ll eventually get so big he won’t be able to move. Obviously that would be really upsetting for me and I think I would have to simply delete the app and just know that he’s not alive anymore. PLS HELP ME!!!!

2026-01-18	Bl*****	I think it’s pretty good because it’s easy to keep the jellyfish alive and I like where you change the lights but only thing is I like the app but you just take care of a jellyfish you can’t even name it or detonate the tank...... but overall it’s a great app to buy and I love how the jellyfish looks so you should buy the app, just make sure to feed it every 4 days and don’t forget about the jellyfish or it will die so get the app! and I have had this app for 906 days so have fun!!!!! <3

2025-01-26	.******	This game is super chill, and you only get ads when you change the water, which you have to do every 3-4 days. I named mine Teacup and he's super cute !! You should definitely check out their other games if you are thinking about getting this. Bye! :3
