so I have some fresh golden teachers and b+ cakes in my terrarium and they have been sitting in there for coming on 2 weeks. Plenty of moisture (im using the fishtank bubbler and perilite). I have been giving them light for 12 hrs a day and darkness for 12. The cakes are covered in myc. however the only growth i am getting is some kinda light fluff stuff on them. kinda stringy. Is this cobweb mold? and what can I do to help these little guys out?
