Thanks for that. Mmmmm - those tigers really are anti-social eh? I do
really like the look of the pentazona barbs - a nice fish shape
instead of the funny diamond shape of the tigers - but I heard that
they were far less hardy than the tigers - is that true? (I can't find
much info on them.)

The other thing I was thinking about was perhaps a small group of
golden barbs with a small group of black widow tetra. They make a nice
contrast in colour and form and seem to enjoy similar tank conditions
and levels of aggression/non-aggression. Do you have any thoughts on
this idea? Also, is there a good algae-eater which will not damage my
plants and not be hassled by barbs (tiger or golden) and black tetras?
I was thinking of otos or flying foxes or small plecs (zebra?).

Thanks ever so much for the barb links - really useful info!
