Anemonefish dads do almost anything to support their offspring

Like the father in ‘Finding Nemo,’ anemonefish dads will do almost anything to support their offspring. Their parenting instincts are so strong that if you give a bachelor anemonefish eggs from an unrelated anemonefish nest, he will care for them as if they were his own. (Any other fish would eat them.) A new study of Amphiprion ocellaris reveals some of the potent hormonal signals that regulate this gallant paternal instinct.
