Observations of a novel behavioural tactic employed by egg‐eating male Telmatherina sarasinorum are described. Four T. sarasinorum males were observed actively courting females of closely related Telmatherina antoniae , enticing the female to spawn, and then eating the eggs. The possible evolutionary implications of sneaky egg‐eating behaviour are discussed.
