The rainbow shark chase the loaches only for a couple of seconds every now and then, pretty much from one side of the tank to another.
The gold algae eater chases the rainbow shark the same way.
The largest Hockey stick tetra keep the other tetras in line.
And the platies(I call them fatties cause they gorge at dinner time) and loaches just want to have fun.
Pretty peaceful tank really. Nothing that I am concerned about.
