I notice when I get new Mushrooms they stay closed up for a day or
forever in some cases. My question is most stores have lights way above
the tanks. I am wondering if when they are put in my tank which the
distance from my power compacts is close to the surface if it might be
a problem. I just got some beautiful purple/blue mushrooms and they
were about 2 to 3.5 inches in diameter. I put them in my tank about 10
inches from the surface of the water and the lights are about 4 inches
from the water and they are staying about .5 to .75 inches in diameter.
They have only been in my tank about 4 hours, and when I bought them
the lights in the store were on for about an hour.

Thanks! Sheldon
