How to remove and cut 5 inch mushroom from aquascape

[Rick's Reviews]

Looking for to advise in how to remove this monster mushroom from my aquascape x 2, it's baby is about 3 inch,
The smaller one is between my 2 rocks.... literally holding my aquascape rocks x 2 together so I can not remove rocks separately

Unfortunately, your best option is to remove the rocks, and break the rock with a hammer and chisel. Personally I use an old flat head screwdriver. I don't see a better option myself.

Is it critical to move them? They obviously like that spot there.
