40 Gallon Tank With Sandfall

[AshP1986]

Hello, 
So I have had livebearing fish for some time now and I am ready to kick it up a notch. I just purchased a 40 gallon tank and want to put african cichlids in it. 
 
I have seen a few of these on youtube.... any opinions?

Interesting idea. Not sure it's for me but there must be a few out there who like it!

I really like them 

 
I have lion's head one that I had in a tank done up to look like a sunken garden. I don't have any pics of it, but I liked it. I might do it again sometime
