RS, great fish pics. How aggressive are your fish? any problems with cannibals?
The African Spotted Leaf Fish, once they get bigger, will eat anything that will fit in their mouths ... and their mouths are huge, given their size.
The Chinese Algae Eaters, once they get larger, are rumored to attach themselves to other fish and suck on 'em. They grown to 12" in the wild.
As far as aggression goes, a lot of it is con-specific:
Larger African Spotted Leaf Fish chases the smaller one.
The larger Black Molly chases smaller one.
The Chinese Algae Eaters chase each constantly.
But there is some inter-species stuff going on as well:
The male Betta was bullied endlessly by the larger African Spotted Leaf Fish when I put the Betta in the tank ... for about 24 hours. Since then the Betta spends most of its time following the Leaf Fish around and threatening it ... by holding its fins erect and flairing out it's gills.
The larger of the two black Mollies chases after anyone that's around if it's trying to feed.
And the Chinese Algae Eaters will chase after other fish.
But there are no fish cowed into the top corners of the tank, and I'm not seeing any real nipping at fins ... so there really doesn't appear to be any actual attacking going on.
