Maybe it jumped out? Check behind the tank. I have had this happen before too. I had a firefish MIA for 3 months! FINALLY one day I went to feed the other fish and I see the firefish really really skinny and sickly looking. I tried to feed it, but it wouldnt eat. Didnt see it for another month or so, then the same thing happend. Saw it really sickly looking. That was the last time I saw it and since then I have re-arranged all my rockwork, so I know hes not in there anymore.
