I will post a video when i back to the states. I had seen a platinum Jardini when they was at size 3". This is at size 30"Looks like a lei to me also the pattern doesn't look jardini on scales or fins to me , I'm pretty certain its not a true platinum either it looks like white tank treatment (hence the white surroundings in the pics)
Sorry to burst your bubble but I wouldn't pay more than £100 for that fish , once placed back into normal aquarium surroundings it'll darken down over time turning more like its natural colours
