I have green phantoms and all I can tell is the basics that work for me: Water very clean, tank they're comfortable in, non threatening tankmates, foods they like, and patience-- doesn't always, but it can take some time for them to get comfortable in a tank.
Video was too short to see much of your tank but mine is sand bottom, driftwood branches, couple of flat rocks against the back of the tank they can use to hide in, NLS or Omega One color pellets fed to the tank in general and Omega One Veggie Rounds occasionally dropped in tank for the plecos every couple of days. Mine love the veggie rounds and were noticeably more active shortly after I started using them. Mine also come out for the color pellets sometimes. I've kept them with a variety of fish, from kapampa fronts to geos, wild angels, rotkeil sevs, guianacara, etc.
