Not that I have any experience with the other species you mention, but I wouldn't do it either. Like the other poster said, the FBT's secrete toxins and if you have animals with completely different needs, I'd be wary. And wonder if it was really worth it to keep animals with different requirements together and whether it was best for the animals. After a few mishaps with my ACF, I've come to the realization that single species tanks are best. Just my two cents.
