White head on green palys? Help identifing

[Tzarnold161]

Noticed this clear head coming out of green palys frag. It looks almost identical to the other heads, but it is white. Is this a pest? Or is it a paly head? If so what might be happening. I am newer to the hobby, any advice would be appreciated. Thanks

Thank you! Since, it has grown it is taking on more color and others have appeared like it. Makes me feel better about them, thank you again!
