Gravel in my opinion. I have one layer of 1" smooth gravel with big sizes here and there.
That was a 16.5" Bichir Bichir for ref

I thnk I finally decided how I want my substrate, Looks really nice man

i never have this problem my fish move the sand around for me

If you vac regularly, or have a tight feeding regimen, or have fish that root up the substrate, you can severely reduce this type of decomposition issue.

Thanks for the input and pictures still undecided though, this is the biggest tank I've ever owned so not sure what to expect with maint.
