Is my Aggressive Clown fish killing other fish

[amdp9]

My second post but learning and sorry for few dumb questions again.
My tank(32gal Bio Cube) is about 8 weeks, perimeters are on place. During week 3, I initially bought two clowns and one royal Gamma. One of the clown died very next day. I thought he was stressed and died.
Then I start to notice that whenever ever I go move any rock work Clown comes and bite my hand. In few days Royal gamma went missing and found out that he died as well. I asked around the local shops they recommended me to but Anemone which will help clown. I bought a green bubble tip and Condy anemone. Later found out that he has the same behavior. Went back to the local they recommended me to add another small size clown than him. He is settled and didn’t do any harm to the other clown fish.
I let the things be as it is. Few days ago, I added two firefishes. I noticed same clown was harassing one of them as soon as he went in to the tank. And that firefishdied the next day. Next day I start to noticed that he start to harass the other fire fish and today he died as well.
I don’t know what to do, I rechecked my perimeters they seem normal where they should be.
Please help and recommend what to do? Should I ever add another fish to the tank if so which one.

Clowns are territorial, some more than others, and can claim an entire 32 cube if there are no competitors.

Your hand is “competition” so biting you is very normal.

The firefish is very meak in personality and easily bullied.

I doubt your doing anything wrong but maybe the next addition is one with some attitude to put the clown in its place.

General rule is most agreesive in last.

I agree. Watch out when they spawn. With this agression it's only going to get worse when they spawn.
