I have a friend who keeps werneri in a tank with barbs and angels and they
are doing fine in alkaline hard water. They really have to work hard to
compete for food against the gluttenous angels!! She feeds them prawn eggs.
I just saw them last night and I don't know if they have spawned or not, but
she mentioned it was the tank with the oldest fish in it (and she had other
tanks with 4 yr old angels)...
