Strange growth on my crocea clam

[Vnghost]

I'm seeing some strange fungus sponge like growth on the underside of my clam. Should I clean it off with a brush or something. Clam fully extends, doesn't seem like its unhappy. Thanks in advance
Top vs bottom side

is it the clams foot?

or is on the entire shell?

Looks like a foot to me.

Directly right of its shell. Like a fungus growth. The foot is attached to a rock. See the top picture of the left side of his shell vs the right side. When he opens up the right side of the shell gets no light that's why I said "under side". Sorry for confusing y'all. But yea I'm unsure of what's growing on the right side of his shell

I'm gonna go with a sponge or some sort if it's growing on the side with little light.

if it's a sponge its from over feeding the tank right? Maybe cut back on the feeding and remove what you can and see if it comes back?

It is on the side that gets little light. The left side gets a lot of light and the shell is clean. So stop over feeding? If it's harmless I'll just leave it. Don't wanna take him out the tank to clean if I don't have to

only if it restricts him from opening up............

He opens up pretty big. It's like his whole body comes out the shell haha. I'm gonna cut the feeding down. I don't wanna pull it out the tank.
