Beautiful for sure and an easy sell.
If you sell the rock, you should be able to buy some nice new fresh rock for what you get...

I have never had much luck ingetting rid of these once established and nothing seems to be able to win when it comes to chemical warfare.

I tried kalk, didnt work.
tried scrubbing, didnt work.

I wound up killing them through light deprivation.
In retrospect, I should have just sold the rock.

How come I never thought of just selling or trading the rock. That's a brilliant idea, gobytron. I have to reconstruct my rockwork to remove that rock, a little pain to do that but I can save at least 30 of the blue mushrooms. For the red ones, I think nobody wants them. I may have a hard time to trade another rock with someone.
Thanks for your input everyone.
