"Gold Heads are notoriously volatile and often lose the gold on their head unless the owners practise WTT (white tank treatment)."
LOL, no kidding. Doh! So why imply that this person might have a mix up in chips, or certs, or whatever? The cert states November 2015, so obviously the OP didn't just buy this aro last week.
WTT is an Asian gimmick used by vendors to enhance color and shine, characteristics that are almost always lost once placed in a non WTT environment - such as the vast majority of Asian aro display tanks. Not exactly rocket science, more like just another excuse to post links to your forum, where more sales can be gleaned by you and your pals.
