Sirius has no attention span. Goldfish have longer memories. After all, they can be trained as well. There are training kits for fish basketball and soccer. We inadvertently trained the ones in the lab back in college by feeding them at the same part of the tank every day. One time I fed them at a different corner, and they went to their usual corner first. They were gulping but getting nothing, so the gulping rate slowed, and they looked around to find the food.
