2 days ago I was walking back from my room after watching 24 and I could only see my female swordtail all alone, I looked everywhere for my male one who is usually pestering her. The I looked behind the tank and on the bench top was the swordtail. I was so pissed off I thought he'd died. I was getting him out when he jumped, so I quickly grabbed him and put him into the tank. He was still alive! He had a lot of dust on him though but he looked ok. So I put some stress stuff in and thank God he made it and is fine. True story... ;D Then I fixed the lid, there was such a tiny gap but he found it.
