Anyone got any ideas on how to not make my Emperor angel such a jerk!?

[Texastravis]

I bought a 7" emperor from someones tank and recently put him in my brand new 300 gallon as my first fish. About 2 days later I added a 7" blue hippo and ever since he has been terrorizing my hippo. Doesnt even let him sleep at night.

I bought the emperor from someones tank and he was in a tank half of the size as mine and had about 5 fish in there with him including a hippo. Could he have really got that territorial that fast being alone in the 300 by himself?

I have been feeding him a lotttt to try to tone his aggression down but even after about 3 days he still chases the tang down.

Any ideas? I was thinking about building a fish trap and putting him in sump for awhile then adding him again later on. You think this would not make him territorial anymore? Or since he has been in the tank already he is familiar with it and will always be territorial in it.

Im not so worried about my 7" hippos as I am with the 2" clowns, 2" yellow tangs, dwarf angels, etc that I will be adding later on....

If I made him the last fish you think he would cope?

I have a lot of angelfish in one tank and don't have any aggression issues. He prob said "oh s*** more room I'm not sharing this with anyone!"

I also would have def. waited to put an emp in.. but thats just me.. try asking someone who knows more than me (like half of this forum). ;)

I would either move it into the sump or other tank for a while, until you add more fish and let them get established, or move the rockwork around and confuse the hierarchy.

Agree. try moving the rock work around.

Use a large mirror to occupy it's time.

Mirror? haha I might try that sometime

No chance at moving rock work around, I foamed all together.

Probably won't help now; but a big, aggressive fish should be added last whenever possible A 7" Emperor is going to claim as much space as possible, and he did.

Put the emperor back into quarantine for a week, then reintroduce him.
Turn lights out on any fight.

the small fish should not worry about the angel, it's unlikely he'll perceive them as a threat.
