Animal activists in China have raised objections
to a stage performer's "magic trick" which appears to involve goldfish swimming in synchronized formations. Some allege that magnets or iron particles have been cruelly implanted in the fish (others suggests that these are not real fish at all...)
The performance is highly reminiscent of one first posted at Neatorama in 2007; that video has been removed, but another copy is available elsewhere on YouTube
. And it's worth remembering that it is possible
to train goldfish.
