The Think Fish Community Creator is a very powerful and unique tool that allows you to enter a list of fish and their quantities to create a 'fishtank' or community of fish. Based on the fish you choose the Community Creator will tell you if any of those fish are incompatible or may present problems in your fishtank. It will also provide you with a recommended temperature and hardness level for the mix of fish in your fishtank.

To use this feature, first either search for a fish using the search boxes or category search on the right. Once you have a fish you wish to add to your fishtank, simply click the 'add this fish' icon and the fish will appear in the 'your fishtank' box, adjust the quantity and click update. Any incompatibilities will be listed below your fish list and you can alter your selection based on the suggestions provided.

If you enter your aquarium size and filtration type at the bottom of the page, you will be given a maximum stocking level and the current stocking level of all the fish in your list. Once you have finished, click on the 'save fishtank' icon and your selection will be saved, ready for you the next time you login to Think Fish. Up to six fishtanks can be saved for each member.
