We are ‘greening’ ourselves to extinction

[SueDonim]

My goldfish would be offended. They are far from being the most intelligent species of fish but their concentration span and learning ability do seem to outweigh that of many supposedly intelligent people.

Fish may well inherit the seas, and I agree, their intelligence exceeds that of many so called higher order beasts.

My Betta fish was quite clear on that point.

I never had betas but my angelfish were pretty clear communicators  - eg "yes, we are ready to spawn but you have put the spawning substrate in the wrong place. If you put it over here we will cooperate". I did and they did.
