Can someone help me find out what’s going on with my Frogspawn what’s that bubble of sort on the side of it ? Thanks


Don’t mind the algae that was during my neglecting phase got it cleared up and taken care of.

Not sure what is going on but my hammer did the same bubble thing and after a while it went away. Maybe getting ready to split?

Splitting head probably.
