What wrong with my Mushrooms

[mark31]

I got this flower pot of Green hair mushrooms from the LFS. They where doing great for 2-3 weeks the all of a sudden one by one they all started to shrink. I had them at the bottom of a 20 gallon nano cube with 70 watt MH. Checked my water everything ok.
Ammon. 0
nitrite 0
nitrate 10-20 not really sure colorblind
ph. 8.2ish
cal. 400
alk. 9
S.G. 1.025
temp. 78-80
5 gallon water change weekly.
I also notice copepods in between the mushrooms and tiny bug like things crawling around. Is it possible that they could be stressing out the mushroom. I recently moved them higher and still the same, any ideas.

are they in low flow? I notice that when i put my shrooms in med-high flow they pout and shrivel up like that. They also do that if under higher light. Some like it very very low and some like it bright. Try putting them under low-med light and in a low flow area and let them be for a few weeks and see what happens.

need to place them on the bottom of the tank. They do not like a lot of high powered light and low water flow.

+1 on the light and they usually like low water flow

I had them on the bottom for a couple of weeks and that is when they started to shrink. They are still near the top, they open but still not all the way. I will try to move them to another part of the tank soon.
