My boyfriend is on vacation and he left me here to take care of his fish (cichlids). I always thought that fish had 3 second memory, at least thats what someone told me. Anyways he usually feeds them really early in the morning, like 5 am, but I woke up today at like 8, came downstairs and was having breakfast, and noticed that all the fish were sitting at the top of the tank waiting for food. If they never remember things then how did they know??
