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.

Fri Oct 07 2022 Strech guy fan lol.

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…

Tue Aug 23 2022 Amillus

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?

Really fun for an ad factory

Thu Aug 17 2023 Ender-Wiggin

Positives first. The game is genuinely fun, the matching part is relatively quick and the skins that are unlocked are good looking. This part gives a fun and easy sense of progression. The leveling system is also quick and gives rewards that generally make it worth progressing. The battle modes are a fun distraction and there’s good variety in all of them, over all I do enjoy the game Negatives. This game is an ad factory. This is the perfect choice if you love watching 45 second unskippable ads for royal match, that also come with 2-3 confirmations that you do, in fact, not want that game. The forced ads aren’t much better at around 30 seconds, which also need confirmed several times. This is the kind of game I like enough I want to support the developers and buy the “no ads” dlc, but for this game the only option is a recurring subscription. There’s a battle pass system, but it’s more expensive than most console games. I expect some ads in a free game these days, but this is on the extreme end. My choices are to watch a 45 second ad for a reward, or skip it and watch a 30 second ad for no reward. I respect that this game needs to make money, but for the love of mercy dial back the ads. As far as cash grabs go, it’s a really fun game, but there’s not enough content to justify the pricing and ads. In the event I get some automated offer to provide more feedback…. Yes I know the ads are optional, yes I know the passes aren’t required to experience the full game, yes I know they help support *insert cost* to provide *player experience,etc*. There is no reason, not one, that I can’t see an ad for 15 seconds and then click one button to close it entirely. I’ll keep playing for a while, but it’s not a game worth really digging into and maxing out.

This is copying a game called fish feed and then grow

Wed Mar 16 2022 Devinn Dominguez

They are using the same things from the fish feed and grow. I downloaded the game to check and sure enough there are many many things they copied. That way you bite players shows a bite animation very similar to the bite animation in feed fish and grow. They are using the exact same fish and from the fish feed and grow. They copied the way the meat looks like when you kill a fish. This is just another scam game trying to make success out of others gain. The game is nothing like how it is supposed to be. Ik that game can be like that but they really didn’t try with this one. They even posted a Tik tok with a video of a the game claiming it was there’s. You can literally look up FEED FISH GROW on anything and find the game I am talking about. The feed and fish grow game is only on pc as well. Game faking what they are is bad enough but copying a game that is successful to make yours look good can not go over looked. I am very upset with the fact that the apple store and App Store would support this is disgusting. Please do not support this game and don’t play it. It’s at stealing and they are lucky the TikTok video I found is gone because I was going to repot every with allot of evidence. Including pictures of the tik tok it’s self and the how they are stealing not only the game but a YouTube’s content as well. Pictures of the the meats side by side to show they are the same along with the the same fish and killing animations. Pictures of the the real FISH FEED AND GROW game on its steam account and it’s page on the internet. Many more pictures of they claiming what there game is and many pictures of what the game actually is. I hope this is enough for at least some to see and either take this down or change everything about the game and make no more similarities to any game and make original content of they own. I will be keeping a very close eye on this game to make sure it’s brought down one way or another. If I could rate this zero I would this is disgusting and disappointing that people are willing doing this
