what species of clown? what other fish are in the tank?
although no two fish are the same and there are no guarantees .. i'd suggest trying. stick with the same species, and find one that's smaller than she is in size (considering it won't have problems with other fish housed in the tank) and they should pair up quite nicely. it may not be love at first site, but it can definitely work! i've had great success doing so in the past with my occys.
