I like these little tetra's! Maybe because they
have a little bit of cichlid behaviour? I bought 8 of them and added
them to my 750L planted South American tank where they rapidly adapted
to their new environment. The dense Vallisneria "wood" soon became their
favourite habitat and territories got established. The male displaying
behaviour is particularly funny. The Emperors will swim in front of the
female or another male and tilt their body like more fish do, but I
never observed the way their pectoral fins tremble alternately with
other fish species! They also chase each other, but without any damage
done. As far as breeding is concerned they did some attempts in the
dense Anubias nana that grow on a piece of maponi wood as can be seen in
a picture below. They probably succeeded, but the Geophagus
steindachneri were always there to feed on the fresh eggs. I would have
to add Java moss for better survival rate of the eggs as I've read and
heard from fellow aquarists, but at the moment I'm resigning with the
fact that all eggs will be eaten on the spot. I still have time for this
as the fish are still young.
