6 gal Multi's project *Suggestions*

Hey Folks,
So I got given a 6gal (23l) Fluval edge by a family member, having owned one of these tanks already which is currently a endler gubby/Cherry Shrimp setup. I understand how the tank runs and can easily manage water changes and tank maintenance. My big question though is does anyone have any experience with housing Multi's in a small tank and if so how did it play out ?
I am looking at getting 1 male and 3 females for 4 total fish. Tank is currently cycling and should be ready in a few days (accelerated cycle by using media from other tank)
Crushed Coral sand and Texas Holy rock make up substrate with heaps of Shells on the way !!!
Any info or help would be amazing.
