Care: Emperor tetras do well with floating plants, open swimming space with some caves and drift wood. They do love plants. Soft water is preferred and they can live in brackish environment (South American biotope).They prefer to be kept in schools of 6+. They will do great in any community tank with fish that will not eat them. Males can get a little nippy at times. They are active and fun to watch. They do well in so American bio type.

They are pretty tough and don't scare easy. In fact I can pet mine. They nip at my arm during water changes. I try and scare them off but they come right back to nip me.
