I think it was in 2002, so my memory's a little fuzzy on the details, but it's quite a big gathering. Not quite Aquashella, but they rented out our ballroom, plus pretty much all of our other meeting rooms, and had aquariums set up in all our big rooms. (We had a lot of meeting space). I was (and still am) an AV tech, so I didn't deal with them much directly, except I remember setting up a wireless mic for their auction. The ACA has not been back to Cleveland, as far as I know. I don't keep cichlids, so I don't follow them.
