The nigriventris are sticked (fixed ?) on something (filter, wood piece, plants) all the day and then, at night they are swimming everywhere in the tank ... as Alfred do now as well
for my biggest pleasure

This was true for me! Last April, I accepted two S. nigriventris from my friend who was moving. They acted exactly like what Birger wrote above, moving constantly around the tank for a couple of days. There are only two of them, and I think this is why they "argue" over food. If one of them is eating something, the other has to have it. Even if there is plenty for all. I believe if I could increase this team to five or six, the arguing would stop, but it's harmless so I am in no rush. They are incredibly active at feeding time, and otherwise take it easy.Birger wrote:Synodontis nigriventris will spend the first day or two moving sometimes constantly around the tank, then they will settle down. They will quickly learn when it is feeding time though
