“This game is a simple chill game with fish. I recommend this game if you like fish are okay with idle clicker games. My favorite part is that there are no microtransactions, so you actually have to do that work.”
“Chillquarium is a quiet, tidy little game—pleasant to play in short bursts or while zoning out. The fish are cute, the music’s calm, and the loop of collecting and upgrading feels satisfying without demanding much. That…”
“This game is one of my favorite interactive screensavers, turn on chill mode and full screen.”

“Do you like collection games? If yes, go ahead and pick up this one too. Its very fun collecting all of the fish, they also grow when you are not in the game and collect you money. It is a slow start in the beginning,…”
“4 months of daily playtime nets you the 100%. Obviously you could force it and play it all the time, but that wouldn't be very "chill", would it? :) It's a fun collection semi-idle game with lots of fishies.”
“Helps me relax in between games stressful games the music is nice You can play it anywhere it needs better decorations helps me not flip after being killed Yea its like owning a fish tank without the effort of cleaning…”

“Not a lot to say here. An incredibly grindy creature collector that has an aquarium concept. It’s fine to play idly but there’s not much there. Even having it as a background app is a bit meh compared to its competitors…”
“If you are ok will a pokemon 'gotta catch em all' mechanic, chill music, lo-fi graphics and satisfying audio queues for dopamine releases, then jump on in. I love this game. But its simplicity is its joy.”
“The fish are cute, the colors of the fully filled out tanks are nuclear cartoon tones, and the background music is fine for a few minutes are a time but the gacha mechanics really start to drag when you are attempting…”

“Excellent and addicting game. Love the collecting.”
“this is the only idle game i've ever enjoyed. i bought it in 2024 and keep coming back to it. it's not overwhelming by any means, but after completing the achievements you can still find stuff to do. i love it & i'm…”
“A perfect game to zone out and relax. Chill music, many collections to complete and the artwork is a perfect fit and lovely. Highly recommended if you are into this type of games”

“This idle game is very shallow and one note. Nothing like keeping an aquarium. No breeding, no tank design, and encourages an endless cycle of buy and sell. The species are little more than colorful dollar signs of…”
“Barely a game at all. You fill the tank with fish, save/exit. Come back later. Sell fish, buy more fish, repeat. Not a whole lot to this game. Quite literally the most barebone idler ever. Just not a whole lot to look…”

“Man I love when my idle game with 0 meaningful upgrades just turns into refreshing the same pack over and over again to get the 1 mythic I missed. Very game. Much Upgrade”
“This game was a lot slower paced than expected, but I've come to like it. I just check in once in a while and see my tank grow. I know I can cheese it by changing my pcs settings but I'm committed to not cheating and…”

“Neat little aquarium idler. Can be played actively by spamming fish food or passively just by waiting the fishies grow up on their own. Admittedly, getting the last golden mythics wasn't the easiest thing to pull. And…”
“the game requires insane amounts of grinding just to get a few fish, and it cant really be considered idle since you have to constantly feed the fish by being in the window with your mouse and actively engaging with the…”

“Feesh! If you want to autofeed, place your cursor about a third or more down into the sand so they can't circle around the food. If you're gonna tab out, keep the game in windowed mode, use alt tab after opening another window, and your cursor will stay put and continue to…”
— a player, Steam review · 92 hrs played“There's nothing "chill" about this. It's got the min-maxing anxiety of stardew valley combined with the endless card-pack-opening-chase-hunt of pokemon tcg. I hate this game and I can't stop playing it.”
— a player, Steam review · 26 hrs played“Chillquarium is pure cozy vibes with a dangerously addictive achievement hunt. It’s super chill, but once you start chasing 100%, you’ll find yourself opening pack after pack, hoping this one finally has that last missing fish. Relaxing, simple, and quietly unhinged in the best…”
