Aquarium Owners Necessity
Although lacking some fish, this app is very helpful to the aquarium owner. I use this to take care of my three freshwater tanks. You just select the gallons of your tank and "add" the fish to make sure there are no issues with fish compatibility or overcrowding. The app will let you know if your tank is having / will have these issues. Fish have descriptions and pictures to help you identify the fish you have / want. Also, it lists illnesses and how to properly treat them. The only thing it needs now would be more fish to chose from! For example, I have a Twig Catfish / Stick Catfish, and it is not in the app.
