I've been combing the archives here, and I'm trying to decide how best to set up a nano shrimp tank. If I use MGOCPM as a base, is Fluorite okay to cap it with for shrimp or should I use sand? I'd like to create a black substrate to show off the wee critters...I'm thinking of getting some neos once the tank has cycled. After reading so many posts, I'm afraid I'm beginning to overthink things. If I chose something like shrimp stratum, do I need to worry about it breaking down too soon? I'd like the tank to be stabilized for a few years if possible before I had to redo it. Thank you.
