No I don't mean lost as in died. I mean lost as in you can't find it ANYWHERE. I have 6 glowlight tetra, or at least I thought I did, I never really count them because they are kind of hard to spot in my tank. Today I was moving some stuff around to add some new wood, after I was done I sat there for a few minutes to watch the fish and noticed there were only 5 glowlights. I thought maybe one was hiding, but I couldn't find it anywhere, I checked under everything, moved the gravel around a bit thinking it might have gotten buried, checked around the fish tank if some way it mysteriously got out, even though I have a lid, and looked inside the gravel vac. The only thing that I can think of is either I never had 6 and am completely crazy, because I know I have counted all 6 at one point, or somehow he got sucked up when syphoning the gravel and I poured him down the drain, but this to me seems highly unlikely since I don't think he could easily fit into the gravel vac and I usually look at the water when I am pouring it out.
