We've stumbled onto one of the following problems.

1. If you're a mac user, Internet Explorer doesn't play well with Shockwave. We wish it would. We hate to say this, but you'll probably be much better off using Netscape to visit the Virtual Fishtank.

2. You don't seem to have javascript turned on so we can't tell if you have shockwave loaded on your machine. That's not a problem, it just means our shockwave detection routine doesn't work for you.

3. If you're a unix or linux or lynx user, Macromedia hasn't made a version of Shockwave that will work with our Virtual Fishtank. We wish they would. As much as we're avid unix junkies, the Virtual Fishtank just isn't going to work for you.

If none of the above applies to you and/or you just want to try out the simulation no matter what, then jump on into the tank. Good luck!
