So, I just looked at my tank and realized one of my zebra danios is missing. I looked everywhere for him, I took the filter apart, lifted all the rocks in the tank, moved all my stuff around the tank and can't find him. I don't know when he disappeared, either last night or today. If he did jump out, how long will it be before I will notice a smell of the fish that I can't find? Also, if he didn't jump out, what is the likely hood that a pictus cat got him? the danio was roughly 1-1/2" and the pictus is only 3". I also have a rainbow shark in there, but I think its more likely the pictus got him if anyone did. I just hope that is what happened and he didn't jump out.
