what are your tank conditions

nitrite, nitrate, ammonia, ph, salinity

also if you could include the type of lighting (although not so important with mushrooms)

 

[BigTruck6o2]

Ammonia is 0, Ph is 8.09, Salinity is 1.023, nitrite is 0, Nitrate is 5ppm, I got 3 175W MH bulbs 5K a piece and 2 acinic blue bulbs

are the mushrooms in direct light?

Yea, there more towards middle of the tank, but the light hits them directly, the 2nd one is almost completely gone now just shrivels up and goes away now the last one is starting to turn brown on the outside, but i got other mushrooms and polpys and all that, which are all fine and growing and whatnot, maybe i just got some bad ones i dunno

could be some wierd bad ones that had some wierd parsitic problem (i dont know of any that affect mushrooms) keep them out of the strong direct light mushrooms prefer dim lighting
