Looks like they're getting ready for an attack. Better watch out...

 

hahaha that so coool lol

 

yep seen this, i dunno how he manages to control the fish or are they taught to it and the guy just waves his hands about

 

and i thought fishes had memory of 10 secs

 

^fish have proven memory that are much longer, they know when they get fed and who feeds them

everytime my fish see me, they come to the surface looking for something to eat

 

lol those are some pretty smart goldfishes xD

 

-lol attack of the killer goldfish

 

It reminds me on some magnetic fish. Someone moves the fisch with a magnet under the table.
