Answer 6

every animal communicates, just in ways that humans are unable to understand! people are naive when it comes to this subject, thinking ourselves well above the rest of the animal kingdom, and in doing so we forget that we too are animals...goldfish do communicate. I have a zebra danio (the last remaining survivor of his school) with a goldfish, they have been in the same fish tank for over a year and I always enjoy watching both of them caressing and chasing each other...it surprised me at first, but now I'm pretty used to it..it seems like they have their own set of signals since both fish are always interacting.  

Answer 7

My goldfish imitates me. He opens his mouth :O and swims back and forth. He does not like the color royal blue. I don't know why. He shies away and hides.
