Fish Eater.io invites players to dive into a vibrant underwater world where survival is the only rule. Starting as a tiny fish, you must navigate the depths to find food and grow. As you devour smaller prey, you earn the ability to merge and evolve into formidable creatures, including sharks and legendary sea monsters. The game features fast-paced 'eat-or-be-eaten' mechanics where you must outsmart AI and other players to claim the top spot on the food chain. Explore various aquatic environments and unlock unique evolutions to dominate the ocean.

Our Expert Score

74/100

Fish Eater.io follows the classic 'eat-to-grow' formula found in games like Hungry Shark, but with a more competitive .io-style twist. You start as a small, unassuming fish in a vast underwater world, and your primary goal is simple: swallow anything smaller than you and avoid the predators lurking in the depths. The evolution mechanic is the real hook here, allowing you to merge and transform into more powerful sea creatures, eventually reaching the status of 'Lord of the Sea.'

While the gameplay is undeniably satisfying—there's a primal joy in devouring a rival that was chasing you moments ago—the game does lean heavily on ads between rounds. It’s a great 'coffee break' game with vibrant colors and smooth controls, though it lacks the depth of a full RPG. If you enjoy quick sessions of frantic ocean survival and the loop of constant growth, this is a solid addition to your folder of casual games.

Good but need no ads

Mon Oct 06 2025 Mom you hhfh

This game is a really good game, but when I evolve my fishes, sometimes I get ads and there was a review that they did not get any ads and they need to do another review and say wasn’t true traders, please no ads and make a fish eater too, and have it have no ads just thing, but have you like a by yourself thing and make it like the ad for fish eater? Thank you. Oh and also don’t put fish on top normal fish on top of the megalodon. Because the megalodon is the biggest prehistoric and coolest fish. Please put me on the important reviews cause this is very important. I’m on my level 12 or 13. What’s my fish and a little bit too much ads

Could be better but it’s okay.

This game is pretty mediocre. The game is simple and isn’t that special but it’s fun for a bit. Something I noticed very quickly is this game uses many assets, animations, images, and more from many other games. It has models of Hungry Shark Evolution and Fish Feed & Grow, or Feed & Grow Fish. Also, the advertisements I’ve seen for this game literally took footage from Fish Feed & Grow… or Feed & Grow Fish. Also, the advertisements used audio from Pungence, a YouTuber who plays games like Amazing Frog and Fish Feed & Grow………….or Feed & Grow Fish. I don’t know if they got permission from these games of content creators but I don’t think so. If the developers did then I’m sorry but I don’t believe you did. Also, this is more of a personal preference but, the survival game, it is the worst. It is so unfair and once you make it to like 1 minute, it literally just turns into enemy spam. Also the merging system is very tedious and just not that fun. Once again, this is just personal preference.

Something you should know…

This app claims it is online multiplayer. It isn’t. You can prove it by putting your phone into airplane mode with wifi off. You’ll still be matched in their “online multiplayer” battles. Now onto the ads - would you play a game on a console like a switch or a PlayStation where you had to watch ads just to play? I wouldn’t. This is that. If you find it fun, which I do, you’ll want to just pay for the ad-less version and be on your way. But don’t try and skimp out because the basic ad-less version doesn’t block all ads. Only interstitial ads. So, you know, more ads. So now you know: this game is not online multiplayer - it’s AI driven, your score is likely not actually on any leaderboards, and the ads are just to waste your time by throwing more time wasting games your way. Bottom line: try it and if you like it, buy the fully ad-less vip version and waste some time in peace, without annoying ads.

Intrusive ads with hidden X

Sun May 28 2023 Yalikethisname?!

So let me start off by saying this game is fun, great if you need a break. However, the fact that ad options pop up after every 2-4 interactions gets irritating. That’s fine, I can live with it as long as the game balances it out, but what breaks it for me is that the developers hide the X button on forced ads unless you repeatedly tap the screen to make it appear after 5 seconds of watching the ad AND it appears for a split section so you have to tap it quickly just to exit the ad. Why would they do that you might ask? To force you to buy one of their 2 ad removal bundles. A subscription for just a week of ad removal, one for $3 and one for $10. One completely removes all ads and one only removes the forced ads. I’m sorry but if playing for 30mins forces me to watch 10 mins worth of ads it’s not worth it for me. Imagine having a 10 min break at work and you spend 3-4 mins watching ads. I’m good, have fun though

Game is fun, Ads kill it

Sat Oct 21 2023 BreadManDev

If it did not have an ad every second, it could potentially nearly reach 3 maybe 4 stars. But no. There is an ad for every 20 seconds. It makes it annoying to progress in battles because it only processes you won after watching a 30 second ad, then it is 50/50 if you get rewarded. Super greedy company. They have a bundle for you to get no ads. What is it like 10 dollars? Only an idiot would buy that. The only good part about the game is the merging. It’s nice to check on the game every few hours but constant playing is not happening. The battle is really not fun either. Survive though is terrible. Only for the reason that things will spawn right in your face so you can’t do a thing. It’s not even like you can see it coming. It just appears out of nowhere in your face. I also beat the record and it never added it.

Love it but what about my no ads package

Mon Jul 25 2022 Troydaboy17

I love the game, truly its fun and once you get rid of the ads its just pure addicting. However, i have purchased every bundle package there is, 2 of which should have gotten rid of the ads. Yet, I wake up today ready to play a few rounds and go to grab my triple offline boost and notice, it wants me to watch an ad. Okay weird, close the app. Open it again, same thing. I check all the other stuff that for my status shouldnt have ads anymore and what do you know it wants me to watch ads. I did not pay the money i did to be told it would get rid of the ads just for it to make me watch the ads again a day later like I didnt just drop $30 on packages for no ads and skins that I cant access anymore. So how we gonna fix this?

Uhhh wow

The squid is too OP but the ads show exactly what it is. The game is actually better than the ads tbh. Its very fun and i enjoy it btw yall who say the ads arent real are not even playing the game. They arent even violent. The game is more violent. I mean theres blood and killing and eating fish i guess idk elliecat is clearly like very young or too old because this is perfect for me, a 10 year old. I am obsessed with this game. It is not violent at all. Maybe a little blood and like every voodoo game or stuff like that, has you attacking players. Its fun and good for boring times btw elliecat please just stop judging. They try to help you since its a little bit complicated. STOP YELLING T THEM FOR BEING KIND

eeeehhhhhhhhh- no

Sat Jun 04 2022 hmmm nty

READ I was playing a game and I saw the add for this, and it was an add of the game I really want. I read a few reviews, and figured I might try it out. (My thoughts were “Welp, I might just buy a knock-off of a game but at least I’d get what I wanted in some way shape or form!”) I loaded in, rather excited and started playing. It is basically a knock-off of that hungry shark game, where you go around eating things. It was not at all what was advertised. I know that games scam you with advertisements a lot, but it just sorta sucked anyways. (And it kicked me out after about thirty seconds.) The only reason I gave it two stars, is because you might like it if you know what your getting. I immediately un-downloaded it, but give it a shot, you never know if you’ll like stuff like it!
