I've seen "mated pairs" on some of the web sites. These are usually pairs that have been used as breeding stock.

The maroons host in BTA's, or at least mine did. If your tank is big enough and you have enough light, I don't see why you can't have both a BTA and carpet. I'd be careful though, I had a really nice condy and then added the BTA. My BTA followed the condy around the tank and eventually killed the condy, so I suspect.

In nature clowns can change sex. Usually there's a dominant female and several males, one of which is dominant. When the female dies this dominant male gets larger and becomes the dominant female, while one of the other males will become dominant.

In a previous tank I bought two juvenile tomatoes, which paired up in their BTA. One became the female, the other, the male. They did breed. This whole process took about 1 - 1 1/2 years. In my present tank, I bought a BTA and three juvie maroon clowns. Already, one looks like it's much larger and dominant; I think this one will be the female. One of the other two is slightly larger and looks like it's going to be the dominant male. All three live happily in their BTA. We'll see if they lay eggs or not.
