I'd use one or the other in the foreground, not both.
Glosso is far easier to grow than HC, but glosso can also get overgrown quickly, while HC grows much slower.
If you've never delt with plants of such small stature, you might wanna get you're feet wet with glosso first. HC can get really frustrating in the beginning till it takes off.
Glosso on the other hand is very forgiving and it should reward you with great growth inside of 2 weeks.
