Poop? Worm? Mulm? Brown algae?
Tank has been accumulating a fine layer of brown on every surface. Today, it looked like this. It reminded me of when I had a few surprise bladder snails and woke up to something similar looking (which turned out to be their poop) on all my plants and surfaces. There are some of this worm-poop-algae-mulms on the walls of the tank as well, pointing pretty much straight up and down. Which makes sense with the flow of the water. I'm thinking all that algae just rolled up into these little chains?
I've got 5 blue dream shrimp in the mail, and I'm hoping they are STARVING. Those boys better be ready to get to WORK. Just kidding, I'm just concerned about the tank and their wellbeing.
5 week old tank with plants only (I committed a bladder snail genocide)!
