Fantastic app. I've tried lots of other aquarium apps, but this one includes all the information I need in a quick and clear pocket format. I can request any fish or plants that I need that arent already in there which is a great feature. The developers were very nice and went out of their way to help me with some advice on getting my tank cycled too.

Easily the best in its class 👍 I have everything loaded in 'my collection' ready and i use the favourites list for potential buys. I'm realistic in that no pocket app will have all possible species, there are just way too many, but this has decent coverage of the ones most often found in pet shops plus they add anything else you need straight through the request feature in the app. The system works very well.... no need for any 'it doesn't have x or y' worries 😊

Excellent encyclopedia app for fishkeepers with all the information you will ever need along with great photos. I use it regularly when buying fish to check tank mate compatibilty, water requirements, tank set up & health issues etc. Its really helpful to have all this info available in your pocket when out and about. Also absolutely 1st class customer service as I had a minor issue (with Google) which the developer resolved for me immediately. Highly recommended👍
