Wondering if anyone knows what the most natural and ideal substrate would be for my massive LTA? I’m going to set him up in a cube tank and am not sure what caribsea sand to use and what the best grain size is.

Should there be rock in the tank? Or is just sand only and some macro algae ok with a bit of rubble? Right now he’s happy wedged between the bottom of a larger rock and the sand bed.

Massive they can be. Curious to size of yours....in my experience sand bed hasn't mattered, my sand bed is about an inch and half all around, its been ability to bury then attach to glass below / shift rock and they will literally shift big rock to get comfortable. Mine does the full tank loop one end to other every few months. They move ... here is mine. Bout 14 inches currently...
Grain size is the usual crushed aragonite not sand but next larger up, probably 1/8 " in size?
