olly mollie chases the girl mollies & our teeny tiny new green tiger barb ( about 1/2 inch big ) chases the big grown up barbs( 2 & 1/2 inches) & yes they do look embarassed as they scoot away from the little upstart
I have only just started up my tank, so I only have 6 Platy's....
2 Yellow/ red fin, 2 Mixed & 2 Orange & black.
The smallest platy which is yellow with red dorsal chases the other of his pair.... he hides then charges at the other one...head butting it at full throttle..
I'm starting to feel real sorry for the one getting bullied..it's much bigger, you would think he would get his own back, but he doesn't he just puts up with it for hours.
Occassionally the others stick up for him and charge at the lil one!!!
The Bosemani Rainbows chase anything apart from the plecs and the shrimp and the Golden Barbs chase the Plattys
The Plattys pretty much don't chase anyone
Nobody bothers the plecs at all
The Cories have their own little underground (well, underwood) community going on and they're pretty much safe from everyone
I have two albino sharks in my tank (oops, they were little bubbies when I bought them), have now found out that they wont tolerate another of the same species. Needless to say, Henry (big shark), hounds the hell out of Sheila (little shark), but she seems to be fine with it, just keeps out of his way - my plec is a sweetie, he is the only fish in the tank that cannot be moved from his resting place, not by anything else in their anyway. Everyone else gets along just fine.
No one chases anyone in my tanks, except for a dwarf gourami who makes little runs at the female. He rushes at her for a distance of about 6" and she escapes by swimming about 2" away. It's actually kind of cute to watch them.
My other two big male gouramis are separated like bettas, each one in a tank of their own except for the corys on the bottom. Their chasing days are over.
Of course the corys chase each other all over the place, but for them, it's all in fun!
One of my maledwarf pencil fish chase everything in the tank, especially all the sparkling gorami, the other pencil fish and the ghost shrimp. Hes now got the name of little b*?@&^d
