Thats funny. I bet you couldn't beleive your eyes. I have a goby that would go in the over flow and end up in the sump. I would take it out then put it back in the main tank. Then a couple days later it was back in the sump. I got tired of bringing him back up,so I left him. Again a couple days later he was back in the main tank. I couldn't beleive it. That was right around the time I felt all the talk about pumps not being plankton freindly was bs. 8) On a side note though he never went back to the sump. The impeller must have gave him one hell of a smack in the tail fin.
