True! There was a paper on that in Dopeia. :-)

On a similar note, Dave "Dr. Fish" Schleser told me during one of our Amazon
trips that there's a species of Rivulus that jumps onto land, allows itself
to be covered with ants, jumps back into the water, then eats the ants from
the surface! I've never seen this confirmed in any scientific literature,
but if true, that's one awesome feeding strategy!
