Ideally, an IP camera with constant feed to a server would be ideal. With the right software you can record nonstop get it to detect motion and highlight it for you. Not cheap, but would be cool and could be shared/streamed as a live view. Just need an underwater camera enclosure and cabling.
Alternatively, if you feed your fish or want to do some exploring then the Aqua Vu would be good. Keep in mind if you do a fertilization program and secchi disk you'll soon realize that the viewing distance is not too great.
