Whats wrong with my mushrooms? Folded outwards.

[Fire_supremacy]

Hi everyone! This is my first post in RC.

I've always wanted to create a mushroom tank, but I'm having problems with some of my mushrooms. They don't seem to expand at all, and I've noticed that some of my mushrooms are folded outwards.

Why do they do this? Its been a few months now but everything seems fine. Why do they fold instead of expanding bigger? Is this a reason due to too much light?

My tank specs are as follows.
Any help will be much appreciated. Thanks!

if you have alot of water flow they will do this. they will also expand like this sometimes in low lighting. what is the gallons of that tank as well as its depth?

Thanks for the reply.
My tank is about 16 gallons, with a depth of 1ft. Water flow is low.

Tap Water

Tap Water

Water conditioners will remove chlorine or chloramine and it will also neutralize some metals which may be harmful to your fish

It DOESN'T remove nitrate or phosphate which is also present in many water supplies (and some providers add the phosphate to help prevent pipe corrosion). Since both nitrate and phosphate are plant (and algae) fertilizers, this can make a huge difference in maintaining your tank. By controlling the nitrate and phosphate, you reduce the possibilty of cyanobacteria, diatoms, and other "nuisance" algaes.
