Orange shoulder tang gets aggressive...
 

I recently introduced my fowleri tang into my DT. It has been 6 days and my orange shoulder tang (juvenile colours, 4-5") has been bullying it unrelentingly. It goes out of its way to chase around the fowleri (same size) and the poor guy hasn't been able to settle down well. It still eats frozen/pellets but nori time it doesn't get any because the OST would chase it away, even if I put two different nori's at two ends of my 8' tank. :twised: The OST before this was the nicest fish, never bothers anybody, just minds its own business. I guess the introduction of another Acanthurus did not help, but I had thought that the general tame nature of the OST would be okay for the fowleri...

I can sense the fowleri is definitely very stressed and I don't know if they'll ever work it out if status quo is maintained. Should I take the OST into the sump for a timeout? Or just leave them be and hopefully it'll subside? I won't consider selling either fish unless it's an absolute last resort, I love them both equally. Any ideas?

If you can catch it throw it in the sump or qt for a week

Put an eggcrate devider in the middle of the tank for a few days
Each one will have half the tank to use in the meantime

I just tried for a good while to catch him, no dice, wasn't even really close.

I could try that. Where does one procure the eggcrate divider in a pinch?

Home depot

Thanks Greg, I'll go grab some tomorrow, still have a bit of store credit at HD. :)

$15 gets you a 2x4 foot piece

How much do you need to run the front to back and top to bottom of your tank ?

Depth/height are both 20", so one piece will be more than I need.

Is there a particular way to have it held up or do I just plop it in there lol?

I woulda offered a piece, but youre close enough to the United Blvd outlet

Cut it so it fits between your 'scape front to back and when you stuff it in the sand it comes close to or clears the surface
You'll have to play with it to make it fit. The idea is to get it tight enough to the front and back panes so the 2 tangs cannot sneak through

Gotcha, will try that.

The fowleri is a really underrated and underappreciated fish, such beautiful colours. Hope they will all coexist and be a happy family haha.
