The "glo fish" just made the paper. As Rampuppy said, they are being used to detect levels of pollution. The focus of the newspaper article was specifically geared toward mercury pollution. Good subject for an ethics debate, kinda like medical technology and "playing God." Elgecko: You mentioned a "That Fish Place." There is a pet shop in Lancaster, PA called,"That Fish Place, That Pet Place" or something to that effect. Coincidence?
