Hello, I had a cory die and I cannot find it. I bought two corys three days ago and a few hours after adding him to the tank I noticed I could only find one. It was driving me crazy all day and so at night I completely took my tank apart. It was still difficult to see in the water as it was foggy from leftover food flakes. He was in a 10 gallon community tank with one other cory and three brilliant rasboras. The tank is starting to smell but I have looked everywhere for this fish. I have checked the substrate, the decorations (all the hollow grooves), the plants, the filter, and even outside of the tank and I cannot find it. Please help!! Would getting a mystery snail help locate the fish?
