Yes, Helene, that sounds logical: survival of the fittest may in this case be survival of the quickest. And she only gets those which dare to be seen ………. or are fools enough to be discovered. There are fry which constantly hide in the Microsorum “bushes”, others stay underneath the leaf litter. She can’t get those – they dart away under cover as soon as she appears. She only gets the ones that move slowly along the panes of the tank without any cover or “dream along” under the surface.
