Mushroom question

[900dublr]

I bought a rock with 2 shrooms on it from my lfs yesterday. I forgot what kind they are, but they are brown. How long does it take them to open back up? Its been over 24 hours. Also do they need to be fed? Thanks

Well it can take a few days...what kind of lighting do you have? That is important. Some larger mushrooms are sometimes fed, but I reckon most people leave it to the lights.
Also depends on water quality - what are your parameters and how old is your tank? If anything is out of wack for them, they may not open up for awhile.
