http://itunes.apple.com/WebObjects/MZStore.woa/wa/viewSoftware?id=307343271&mt=8 Invertebrate Pocket Reference is a guide for marine aquarists. It will help you to determine if the animal you want to purchase or collect is suitable for your reef or saltwater tank. You will learn the Latin name of the animal, its size, diet, behavior, lighting requirements, whether it is reef friendly, venomous and more. This app is a work in progress. It will be updated frequently with new invertebrate, search features, and links to web sites. This is the second in a suite of apps for the aquarium hobby I will be releasing a Marine Fish reference and a Coral reference very soon.
