Brown spots on bubble coral

[tuajia]

Hi guys, need some advice. Recently my bubble coral started bleaching and receding, suspected that it was due to the recent hot weather (temp hit 29 even with fan) so I moved it to a much cooler tank in my office to recover. After one month the bubble started recovering but started to have some brown spots, looks like small stains. I Googled brown jelly disease but it seems to look different. Should I be concerned? Any experts can advise? Thanks

If the bubbles are not deflated and it's not melting down, then I suggest you just monitor and observe it for some time.

Once it melts away to a goo, remove it immediately.
