Ok, on Sunday night I fed my fish and had 4 Peppered Cories and 6 Neons (plus an unnumbered quantity of Cherry Shrimp) all in a perfectly fine 29 gallon tank. Monday afternoon I did a water change and went to feed them 2 hours later and only had 4 Cories, 3 Neons and the Shrimp. I know I didn't get them in the water change - I was watching the tube for Shrimp... So I have been looking and can't find any bodies. So, today somewhere between early afternoon and now I only have 2 Neon's plus everybody else. Again, no bodies. WHERE did they go? Water parameters are all zero (Ammonia, Nitrite and Nitrate). Have my Cories cannibalized my Neons? No one has been showing any symptoms of disease or stress, although the Cories have been a little skittish, and I haven't introduced anything new. Ideas?:huh:
