Birds nest issues

[Cichlid Dad]

This is a hybrid bird's nest from a tank spawn I don't remember the name, anyway I have bubbles coming out of the coral. Everything looks good on it except for the bubbles any clue? And no I don't think I have a bounce bird's nest

Maybe this? I didn't read the entire thread so apologies if it's no help.
