I don't think there are too many places where Moggies live in open sandy
habitats. Maybe on some wierd Fraser Island lake where you bathe naked they
do.....they probably just all come from all over the lake to see the
spectacle (or to catch the worm) hence why they are out in the open.
I think the aggression is related to many factors and that it won't be
possible to generalise. I think as many folks have mentioned the tank setting
seems important. I couldn't believe when one day at John Cousin's place he
had 3-4 inch Dalhousie's spawning in a 4ft tank with rainbows and angelfishes
and they never bothered the other fish a bit. Being a crazed plant person he
had a reasonable amount of cover in there. I've always found Dalhousie's to
be pretty nasty. The fish we collected from the Valley of Lagoons in the
Burdekin are nastier than normal according to Glenn Briggs who keeps a number
of Moggies. I've found Murray-Darling moggies to be peaceful whether kept in
bare tanks or otherwise. I think keeping moggies together is definately a
fine art similar to keeping nasty cichlids all together.
I also have to agree strongly with others who mention that keeping them well
fed is important. I've noticed carp gudgeons (not Hypseleotris compressa, but
the other south eastern Australian ones) get nippy if they go hungry.
