Once upon a time... I had a gigantic one. Then I moved. Rather than seeing it destroyed and the fish die a "shaken, not stirred" death, I sold it for pennies on the dollar. This from the aquarium stream. The aquarist who started it had no other contributors. So, I joined it and posted a few —hopefully better than this. I don't think I've helped. Grayson hasn't posted since I started posting. LOL.
