to soil or not to soil
I just bought a 5gal tank for my betta. I think I basically want to make it a moss tank so I can eventually add cherry, amano, and ghost shrimp and give them a nice atmosphere to live/hide in. I am thinking about covering the whole botttom in moss and shaping some hills out of rocks or just the substrate to give it depth. I might also a nice piece of driftwood or a moss tree and maybe a big sword or crypt as a focal point.
So for substrate, should I just do cheap gravel/sand because moss doesn't really have a big root system and then under the crypt/sword just put root tabs? Or should I do miracle grow organic potting soil capped with sand/gravel?
I saw play sand for sale at walmart (to either use by itself or cap the soil with), but it had crystalline silica in it, is that safe for aquariums?
Is using dirt hard to do? I don't want to have to do a ton of maintenance etc.
Thanks so much
