It sounds like they are making a video for a potential buyer. In the beginning the guy says, "wow these fish are so non aggressive/friendly", "they look so pretty", "if they swim into this net they"ll stick", "ok lift the basket higher", "ok ok they get the point".
Ive seen this video before. We call these mekong datnoids in Vietnam. I have been saying for a long time that these new small ST looking datnoids are VT not CT.
