Hello, I was wondering if these fish are compatible with my 3 inch clown triggerfish.

Chaetodon semilarvatus(Addis Butterflyfish)
Chilomycterus schoepfi(Spiny Boxfish)

I'm going to put either one of them, whoever is more compatible.
My tank is 75 gallons big, it's been set up for about a year. I have a 29 gallon tank working as a reef/refugium along with a wet/dry sump so I'm sure the bio-load won't be a problem when I add one of the two fish. I would really like to add the Butterflyfish and have heard that it is possible to keep them in the same tank with Triggers, but not certain and do not want to get a beautiful fish get killed so I thought I should post first. Any replies would be great, thank you

well there are exeptions to every rule....but ..those are two kinda sensitive fish that you would be putting in with a real brute

Watchout those butterflies can tear apart those triggers when they get bigger.

butterflyfish will tear apart triggerfish?
not triggerfish tear apart butterflyfish??

I wasn't expecting that one. This is what Robert Fenner said from wetwebmedia.com

Clown trigger and Chaetodon semilarvatus
Hello Mr.Fenner,
<Author/friend Anthony Calfo here in your service>
I currently hold a 75 gallon tank that is about a year old supported by a 29 gallon reef/refugium. In it, I have a 4~6 inches big juvenile Clown Triggerfish.
<beautiful>
Would semilarvatus get along with the clown? I plan to make no more additions after the butterfly.
<not at all... truly unatural and inappropriate mix. Even if the trigger did not impose aggression, its presence and posture are a threat and stress to the butterfly species. Alas...you need another tank <wink>. Kindly, Anthony>
