Weird FaceBook Feed From My LFS

I saw it yesterday too on the magazine Practical Fishkeeping's page. I find it neither cruel nor weird - I think it highlights how skilled and intelligent fish are, something which is vastly under-estimated. The more people learn about how intelligent fish are through examples such as this, the better people will hopefully value and treat them, rather than consider them lower down the pecking order than other pets such as dogs.

There's a training kit called the R2 fish school training kit (from recollection) which some goldfish keepers have used and their fish love the stimulation. I think my goldfish would have loved it too but sadly he died before I heard of this.

Fascinating what they can do, isn't it?
A friend posted a video a couple of days ago with a betta jumping through a hoop held about an inch above the water.

If I was less of a luddite with social media I'd post a link
