Clownfish time out

[Vikkireef]

Hi guys

i have a 90g mix reef so far all good till one of my 4 clownfish started being a bully to another one


I will call them
1.- the bullied (Wyoming)
2.- the smaller (black)
3.- the biggest (oxy)
4.- bully guy (normal clownfish)

they were fine but like a week ago 4 start biting and crashing 1, 3 is the biggest and dominant she make all do the seizure thing, 2 is just happy and loving my nems (I have 2 nem)
So fb groups recommend the mirror technic and the clear box technic (I'm doing both now 4 is in the breeder)
4 bite 1 chase him and even took a piece of the fin he is really aggressive towards 1 but only him,

How long should I keep it? What else can I do?
Any help would be appreciated

What you are seeing is not at all unusual for clowns. Isolating the offender might get it to reform, but it also may not. You may need to sell, trade, or give away the fish. Some just will not live with other clowns.
