### 5/5 — Awesome! Updates?

*2026-06-04*

This is an incredible classic!! I do have a couple needed updates! The fourth tank - the big scary monster fish is labeled 1,000, it’s actually 10,000 shells. Also please add the toggle switch in the Virtual Tank to turn the fishes names off that were bought in the store! Thank you so much for keeping this gem alive I’ve been playing nonstop for two days!

### 4/5 — Rainbow guppy

*2026-05-05*

As someone who has been a fan of Insaniquarium for over 15 years, this port is pretty dang good. My only quip is there is no rainbow guppy (or carnivore, for that matter) in the Fish Emporium! Would love to see that changed, as I was so excited to buy one of these. I’ll play the game regardless but please put the rainbow fish in the store!!!

### 5/5 — Chinese players

*2026-05-04*

hope the game support chinese

### 5/5 — Happy with this game

*2026-02-01*

I’ve been really wanting to play insanaquarium but have a MacBook so I was struggling to find a way how. This game quenched that thirst. I’ve only played a couple of rounds and I’m not happy with the aliens, they aren’t very good at eating fish, but other than that it seems like a pretty perfect replica so far!

### 5/5 — Perfect port

*2025-12-05*

Perfect mobile port of a great game, there’s another particular port that crashes on level 3-4 so I was very relieved to see this work flawlessly 🤩 Also love that it’s a paid app to negate micro transactions !

### 3/5 — Fish aint dying

*2025-10-05, version 3.6*

So its all good till i discovered that the aliens aint killing my fish.Could u please fix this bug.Paid for it cant get the full excitement cuz of this

### 5/5 — Excellent work!

*2025-10-03*

Great game! Very good reminder of the nostalgia version we used to play. I wish they can expand the screen to fit the entire phone though but that might be hard… Excellent work!

### 5/5 — OMG! EEEEEEEEEEEEEEE

*2025-02-24, version 3.1*

omg this you gotta be kidding me IT’S THE SAME AS INSAQUARIUM DELUXE!!! 🫠😱😱😱

### 5/5 — Great so far!

*2025-02-14*

I’m hoping to see some more updates. It’s not perfect yet, but the best I’ve seen on the iphone/ipad. Please continue to update! Thanks so much!!!

### 2/5 — Memories

*2025-01-17*

I would say that I love this and that you’re doing a great job bringing it back! Was disappointed though that the scaling is problematic on the iPhone 15 pro max. Would totally leave a positive review though if it scaled properly and would be tempted to revise this review if it’s fixed in a later update.
