OK so I've had this 5gal fluval chi sitting around empty for awhile. I had similar setup a couple years ago with glosso. This time I had micro chain swords laying around. So i figured i would try DSM with it.
I've been thinking of going back for some more i will try to get the name then. Yeah just make sure there aquarium safe. I think these were around .50 cents a pound i think. I remember having a large box full for under $20
Keep it all chain sword if you're going for that "look" because if you start adding other plants it won't look like the clean setups you see. Which is fine, do what you like, it just doesn't look like that's what your intention was by looking at the rock placement.
Nice to find a fellow "Dechier" around here lol. I like the layout. I would have used a smaller accent rock since these aquariums can get hardscape-crowded very easily, but this might turn out into something interesting.
