I know that I wouldn't try it. Or at least I wouldn't if I didn't have another tank set up, to take one of the pairs.
While my pair of pink skunks are fairly peaceful, they can get a bit aggressive if any other fish comes new their anemone.
Sure that someone has tried it and had good luck, but wonder how long that has been working, 3-6 months isn't long enough. Heck even a year isn't long enough to say that it is working.
