Calm down bullys???

[Tham704]

How do I keep aggressive fish from antagonizing the rest of my 75 gallon tank? I've read everything I can find on the subject. Any hints that might help?

Is this FW or SW?

Fresh water..... The fish in question is a dempsey ciclid. There is another in the tank with 2 unidentified ciclid. This behavior started about a week ago.

Positively identifying them is absolutely necessary. Some simply are not ever compatible with others. Can you get pics?

Try changing around the decor to make them each establish a new territory in the mean time. What size tank?

75 us gallons. I know it's hard to see. I'm taking photos with my phone
