2Poor is correct. Find sheltered/shaded areas in your rockwork. How long have you had them? They take a little while to get going, but once they get established they'll take off in size and numbers.
Hi,what about blue or purple mushrooms?What are their requirements then?Does the intensity of the lighting change the colours of shrooms?And if so,would a blue turn red,green or brown, or in what sequence under what type of lighting?Hmm...
I have never noticed any correlation between corallimorph color and lighting requirements. That may just be because they all require so (relatively) little light. I have never had any mushroom change color on me. At least not to any significant degree. Nothing like an sps does.
I have red kobolly shroomz and they do seem to like a little more light than the blue or green ones. If i ever put them in the shade they allways reach oyut and trumpet searching for light. When they were moved out into the open they blew up massive. But on the other hand i do only have flourecent bulbs but it still works out to 5 watts per gallon.
