That isn't bleaching, that's tissue necrosis.

What do you think could be causing it ?

As far as I've read there isn't one known cause. It's a maricultured piece and they're not accustomed to captive life. I would start with parameters and flow and lighting.

RTN (rapid tissue necrosis)

Causes are numerous. But it could be anything like water quality issues to unstable parameters. If it continues to worsen cut just above the bleached area and hope for the best.
