Jim,
And just so you know, if one of your fish swims up and waves a fin at me on "tap on the glass" I may fall out of my chair.
Although thats not a bad idea as an Easter Egg. I can see it now. Set it to only happen once every 4-5 thousand key presses of that particular choice. Whatever fish is closest to the glass at that moment swims up and waves a fin and winks at you. People would look like cjmaddy's avatar going crazy pressing keys over and over just to figure out if what they think they saw was really what they saw.
