i have had that same question all along too. found some dvds on amazon and overstock, and Nat. Geo. has something on the amazon when it floods and shows an aro for about 5 sec. but thats it... would defenetly wach fish tv. maybe we should all write emails to Nat. Geo. and Dis. Ch.
dunno they where eaither at amazon.com or overstock.com just type in fish or aquariums and then click on videos and they had a bunch, like FW and SW and planted and about aquarium fish i think.
