Viewing Tank - help with substrate ideas

[Snoopyslim]

What sucks imo is that I love the look of the coconut husk when its has that nice deep rich brown color.. but when it dries out, it just looks meh. I was a little disappointed the first time I used it and it turned to a light brown dirt. But it definitely needs to be dried in advance or you will get fogged glass. Picture of the enclosure?

I am embarrassed to admit I don't know how to post pics in a forum LOL but I will put one up in my images.
