you aren't gonna believe this one. ok, maybe you will! :D
today i was blowing off my rocks (regular maintenance stuff), and happened to see some bits of the torch floating around. sucked up what i could w/ the turkey baster. couple of these were on the sand, and appeared to have attached themselves to the sand. so! i put them in a specimen container drilled with a few holes for low water through-flow, and just set them on a large frag disk.
now! what the heck do i feed em? should i just put a few drops of some amino acid supplement in the container?
side note, you can really see led banding in this photo! lol i had the canopy up 90* facing out into the room and shooting down into the container.
