Two boxfish arent getting on...

[kronin]

I've had a Caribbean Boxfish for about 4 months now, and have just added a yellow spotted boxfish aswell. Both fish were bought from the same store - and the gentleman there assured me that both would get on fine. Well they dont!
As soon as the yellow-spot was released in the tank the carribean started circling around it, and taking nips of its back. Its been a couple of hours now and he's still harassing the poor little blighter. I say little, hes about an inch..... square , but the carribean is only about 1.5inches.
The yellow spot isnt showing any signs of retaliation, he just gets away and hides until the other one finds him.
What do you think I should do ? Ive read mixed opinions on the toxic abilities of these fish. Most just say they contain toxins that if released can wipe out an entire tank - others say that there has been very few recorded cases of this happening, and its very unlikely to occur.
At the moment im just keeping an eye on them both. The yellow-spot is getting better at keeping away from the other one - but as soon as hes spotted hes attacked. Should I leave them for the rest of the day and see what happens ? Or do I have to drastic action and take one of them back ?
Tank is a 75gal btw - only other inhabitants is a largish Clarkii clown and 3 yellow-bellied blue damsels.
Thx in advance.

I disagree that it seldom happens. I have heard of many cases (had one myself with a boxfish I bought) of tanks going bye-bye from a toxin release by Boxfish. If they had gone in at same time it would have been better and the chances are they would have worked it out faste. If it were I then one would go, but that is my personal thought on your situation. My reference books state tho no boxfish with another boxfish. Another point is whether they are same size or if the older tank one is larger then the new then that can be the cause of the fighting. Something else to consider is how large they can get and it is only a 75 gallon so down the road there could be that problem to deal with.
