Sudden Agreession

[djam]

So I have a 100g tank, everything was very cool. then we added a small yellow tang and all the fish because super agreessive towards each other. The 4 clowns which used to swim in a school with the xs blue tang now chase each other. THe tang is rarely involved in any of the agression. All parameters are good, but even the mandarin shows signs of fish picking on its tail. the four clowns lived together happily for 4 weeks so far. Any ideas?

Tank members
Mandarin goby
Diamond goby
Red spot blenny
2 black clowns
2 orange clowns
yellow tang
crabs, snails, etc.

From what ive read, even in a 100g tank, 4 clowns will eventually fight for territory (it also hapened in my buddies tank)
About the tang, try to QT it for a while and see if things go back to normal...
If not, then u know its not the tangs fault..

They will establish hierarchy and all will be well in a week.

Agreed, as long as no one is getting torn up, leave 'em be. Chasing them around with a net is just going to stress everyone out.

Ok, ill give them another week. With all the crazy rick structures i cant imagine catching anyone.
