Invasive state of the regal demoiselle in the southwest reefs of the Gulf of Mexico

It has been described that the introduction of a first invasive species to an ecosystem can trigger the invasional meltdown process, where ecosystem interactions with first invader facilitates new species invasions (Simberloff and Von Holle 1999).
      This process could be happening in the reefs in the southwest of the Gulf of Mexico. The regal demoiselle (Neopomacentrus cyanomos (Bleeker, 1856)) is a native damselfish of the Indo-Pacific that was first recorded in 2014 in the Los Tuxtlas Reef System, in the southwest of the Gulf of Mexico (González-Gándara and Cruz-francisco 2014).
   Neopomacentrus cyanomos is now established and to date it has spread in the Atlantic from Banco Campeche (Robertson et al., 2016a) to north of the Gulf of Mexico (Bennett et al., 2019).
