Anglefish aggression

[btackerman]

Good evening everyone, I have a annularus anglefish that I have had for a few years and a coral beauty for the same time frame. I just purchased a emperor anglefish and the annularus is showing a lot of aggression and so is my regal. The annularus is a full adult and the emperor is almost done transitioning. Is this something that I have to wait to die down or is there something that I can do to reduce. I also have a 400 gallon system.

I’m thinking you’ll be OK in a 400-gallon tank. Any chance (if necessary) of using the old ‘small tank’ trick of mixing up some rock work to throw your established fish a curve?

 

[btackerman]

So similar to what you would do with tangs

 

[btackerman]

So I have rearranged my rock work and the aggression is still there. Do you think this is a wait it out or will the annularus eventually kill the emperor

 

[JumboShrimp]

Is it relentless, 24/7, or only when they meet-up for a quick get-outta-here chase?

 

[btackerman]

When the emperor comes out it is then chased

Following. I have a new juvenile queen that was viciously being chased by another established angel (now removed and in acclimation box). Hoping aquascape change will do the trick. Maybe add more fish to disperse aggression. Not sure tho as it was very intent aggression.

If you can get your hands on an acclimation box, stick it right near your aggressive fish’s favorite spot— so he has to learn to ‘tolerate’ your new fish. As an alternative, go to Lowe’s and get a large piece of egg crate and divide off a section of your tank for a while; zip ties if you need for than one piece. Use rocks or magnets (like from Flippers) to hold the dividers in place. I have even used large sheets of plexiglass to divide my tanks for new arrivals.

They will sort it out. Your annularis & regal may not like the outcome. Emporers are pretty tough customer's. 100% honest I love my emporer but it can be pretty annoying with all the chasing/barking.

what do you mean by they may not like the outcome?

I wish I could do those ideas and should have thought about it first, unfortunately there is no getting a fish out of my tank due to it being a 6’Lx4’Wx3’H

 

[JumboShrimp]

No, for the egg crate or plexiglass dividers, just spook your Emperor down to one end and drop the dividers down; or use them to corral him to one end. It’s easier than it sounds.

Those are pretty passive Angel's in comparison.

It's a 400, you should have room to put egg create in the corner for several days, works really well and easy for feeding.

Photo from my build thread, yellow mask angel. Hold in place with 2 cleaning magnets.

Dollar store mirrors taped around the outside of the tank helps too. Just pop them out of the frames they're in to sit flat.

My koran tried to kill my emperor relentlessly for a month. Then it became every once in a while but it never goes away completely.

 

[WVNed]

I have a 240. I kind of wish I had only went with one large angel. My koran has a very bad temper.

 

[JumboShrimp]

Very beautiful collection of fish you have there, so I hate to agree with you, but if there was one combination of Angels I wouldn’t be brave enough to try it would be an Emperor and a Koran— unless the tank was huge.

Ah so I did not specify it is a regal tang not a regal angelfish

Your fish look healthy to me I guess I did not realize that adding more is similar to tangs and same thing with aggression.

 

[WVNed]

I have tangs. Angels are worse. Tangs have little tiffs now and then. Angels get mad and stay that way for a while.
I just added a tang to this tank. 2 days in an acclimation box and no problem. With the angel it took a month.
The large angels do not bother the dwarf ones. I have 2 bicolors in the tank.
