Once again, this boils down to what you WANT to do. People quickly take the stance of what is NEEDED or NOT needed, and avoid the issue of what you WANT to get.
I don't believe condy's are typically host anemone's, so it really doesn't surprise me that anyone's clown didn't take to one.
Certain clowns are more apt to taking to certain anemone's. However, yes, it is true that there are no guarantees that any clown will take to an anemone. There are many compatibility charts available. Here is one:

Personally, I have a very large BTA. I put it in my 29g after it was set up for a couple of months. My tomato clown took right to it, and they have been inseparable ever since. Now, 5 months later, it has grown substantially, and is now in my 60g as of this weekend, happy as can be.
Anemone's such as BTA's greatly benefit from having a clown. They offer protection, and assist with feeding as well.
If you have the setup for it, and want an anemone, I say go for it. They need good lighting, and meaty foods in addition to filter foods, as well as good circulation.
The only thing I would currently criticize is that you didn't do any homework on this before you jumped in. Anemone purchasing should not be done hastily. And the fact that you don't even know what kind you have is concerning. But now you're in it, so......research, research, research!!!
