This app works and helps a new aquarium hobbies to out by preventing you from choosing to put non compatible species in the same tank, hopefully newbies will know this means they aren't supposed to. However, it could be improved a lot and have more functions (like a search bar), or have more animals such as a turtle/ crayfish/ frogs/ the kind of animals that go into tanks with fish. It's because of this apps lack of breadth that I'm giving them only 3 stars. Hopefully they improve from being a "list" only about fish to the realization that aquarium hobbyists have many other things in their tank with the fish. It would also be nice if it took into account filtration and water changes though because someone who doesn't plan to clean wouldn't want a full tank and someone who plans to do so excessively can have a higher bioload.Other than this, the app is nice for planning a tank.
Needs work

It needs to take into account that some fish, even if they're small, don't do well in small tanks. In the app, I put a molly in a 10 gallon tank and it said it should take up 2 gallons. So at least one molly + other small fish + shrimp perhaps should do nicely in a 10g? Mmm, no. In my experience, that works horribly. I had a molly, 2 platies, and a shrimp in a 10 gallon and after the initial excitement of new fish wore off, I realized that I knew deep down they weren't happy in this setup. I returned the molly to the store and got two more platies to add in her place. The four now seem to be happy as clams, and healthy too. The whole tank used to be riddled with health problems while I had the molly in there. Imagine if I'd initially added mollies to my tank according to the app's suggested ratio of 1 fish:2 gallons...The app really needs to look at the specific needs of each fish more in depth. Some produce more waste than others. I think the app would do good to change the minimum tank size for one fish of a species to the min. tank size for the least # of fish in a school required for them to be happy. (Mollies really shouldn't be kept on their own without others of their kind, and given they're livebearers... Yikes! You're definitely gonna need more than 10 gallons.)
No Aquarium or Aqua-Scape designer should be without

I have four aquariums that started as artistic Aquascapes that turned into planted Aquariums. From works of art to growing lots of Lucky Bamboo with rocks, driftwood and grass all over glow in the dark substrate.I started selling some of my Lucky Bamboo and made gifts out of them as well. I use all kinds of Aquarium safe crystal’s, many which are blacklight reactive. I was hesitant to add any fish because when I was young my attempts ended in disaster for the fish.But I love Male Betta Fish and have a new interest in fish that glow. I didn’t know where to begin until I found this website and guide. It gave me the confidence to add fish to each of my four planted aquariums. Lots of great information and beautiful pictures of the fish. Most importantly for me is the information about PH and Temperature because I have to match the right fish to the ideal conditions of my plants. Highly recommend!
Did not meet expectations

I stumbled across this app and based on the description and pictures in the App Store, it sounded awesome. I downloaded it and began to “set up” my tank in the app and add my fish. I tried to add an African cichlid, but found out you need to pay $2.99 to access any type of African cichlid. That was disappointing because it said nothing about an in app purchase in the description… SoI thought I’d go look up some of my other fish in the glossary. They have a basic list of common freshwater fish, but then an in app purchase to view any uncommon freshwater fish, any African cichlids, saltwater fish. You need an in app purchase to view plants at all. The care and maintenance tab is a list of diseases that from my perspective would be very uncommon. It doesn’t cover any of the basic diseases or other problems you’d run into. And it doesn’t say anything about tank maintenance. Overall, I’m pretty disappointed with the app. Even if I were to purchase the upgrade, half of my freshwater fish aren’t even listed.
New onboarding, and improvements to tank setup flow. Plus performance fixes and polish across the app.
