mushrooms i find are one of the hardest things for ME to frag! As is my kenya!
They get all slimy so u cant glue them...*******!
U can take a razor blade or hobby knife to the base of the mushroom! When its free...take a tupaware container with some LR rubble in it and put the mushrooms under the LR. They will attach to a new piece and climb up to the light. The tupaware will keep the flow from blowing them away as well!
Honestly u cant kill these lil buggers...ive heard of people putting em in blenders and puring the goo back in the tank and ending up with 100s of lil shrooms all over!
U can put em in the dark and they will adapt and survive! Believe me a very hardy coral mushrooms are!
