Help, is this brown jelly?

[Tinklez]

Hey everyone. I just bought this splatter hammer which was opened at the store when I bought it, but had never fully opened since coming home 2 days ago. Today I noticed this white/grey gel forming over one of the heads—is this brown jelly disease? Should I remove the coral and cut my losses?

its hard to tell with the blue light. it doesnt look good though. can you take pics with white lights?

Picture in white lights will help more.
How close is that goni, was it able to touch the hammer?, Red goni's have a powerful sting
