Clam likes to touch glass

[this is me]

Is it alright for the mantle to touch the glass? It keeps on moving toward the glass!

Mine too. I have moved it back about 3 times and over the course of a week, it goes right back. I don't know if it is o.k. or not but I finally just left it where it wanted to be and it seems happy.

sometimes they will do this if they are not getting enough light, they move closer to the glass to catch reflecting light as well as what is coming from above.

not enough light? I'm using 250 DE!!!
the maxima is about 20 inch directly under the MH.
I'd thought that it was too much light.
