A fly swatter! Too funny! I know what you mean about freaking out the fish though, I sometimes wonder if some of mine are shy or holding a grudge for something I've done. At least I know it's not from photography, at least lately, still no camera.
Of course, hubby chasing him about the tank with a flyswatter to get him to puff up (didn't happen anyway!) did not help the situation. Bad hubby!
Petland in Geneva, IL has had a variety of dwarf gouramis. I got a gorgeous, healthy powder blue male and they have ordered a female for me.
