While I was taking a video of a pair of Paraneetroplus bifasciatus 'Rio Chacamax' in the midst of spawning, a sudden attack on the egg plaque was carried out by a female P. melanurus. The parents successfully fought off the intruder, but not before a few eggs were dislodged and eaten. Here's the 'hit and run'.
