Bullied Cories

[fish mad]

My rtb shark just wont leave my 3 bronze cories alone. Its strange he doesnt bother my 2 jullies . Does anyone else have this problem?

I had the same problem with black ruby barbs, I had to get rid of the barbs in the end because they were biting the bronze cories fins.
I have albino cories as well but they never bothered them, maybe it is because they are darker from above they confuse them for another type of fish.
