FishBase is an amazing tool for both scientists and aquarists. But it can be chore navigating the web site, and not all the mirrors work equally quickly all the time. FishBase Client speeds Things Up by making searches easier and by providing a quick way to toggle between Fishbase mirrors around the world.
Credit where credit's due: while this program doesn't use any FishBase data directly, I'd like to make a point of acknowledging the awesome work done by the FishBase team.
