One final point worth mentioning are aquarium clubs where many fish keepers gather to show off their fish and possibly sell some
. You'll probably see an excellent range of species including some very rarely available and will have the chance to chat to experienced fish keepers. Once again the one concern would be that the fish may have traveled some distance to get to the meeting and you'll need to be aware of what will happen if the fish die soon after getting home. Try to take the details of anyone you buy from to be able to contact them in the future with any questions you may have.
