So after all this talk about MTS taking over the world, I decided to take a good look at my tank. I have reddish Fluorite topped with pale play sand so I though maybe I just wasn't seeing them. I looked and looked. Surprise! I found one! I looked some more and as I kept looking, a grim realization hit me: what I used to think were Fluorite rocks were SNAILS.
These were just the ones I saw at the front of the tank. I shudder, literally shudder to think of how the back of the tank looks. Everywhere I looked, now that I knew what to look for, I saw little spiral shells.
Sooo, uhm. Do you think my koi can eat these?
