There has been cases proved that animals know, feel, hear, and see first than humans. They can tell when something is about to happen before it happened. I haven't experienced or seen it before but I had a friend who saw some animals panicking and acting weird before the south east asia 'tsunami' hit the coasts. So animals are actually connected to nature.
So about your fish, he could have a better instinct or is more connected to what could happen before it happens than all your other fish. Not really telepathy. Hope this helps
