Horse Face Loaches

I would like to get a couple of "horse-face" loaches for my planted tank.
I know from experience that these guys get going 90 mph across the
tank and then just imbed themselves in the gravel.  They look like arrows 
shot.  I am wondering can i put them in my planted tank.  I have 2 lines of 
thought ....

1) They will slowly turn up the gravel , and be considered good.

2) They will tear up the roots down there.

The ones I am considering are about 2.5 inches long.

Any one have any experience with these guys ?
