The following types of earth-eating sea bream are docile and non-fighting:

* Santarem moon gem: The body length of adult fish is generally 10 to 14 centimeters. It is a beautiful South American cichlid ornamental fish species.

* Pennydale: It is a special type of fish. This type of earth-eating snapper has a relatively lazy character and will not actively attack other fish.

However, please note that although these earth-eating snappers are generally docile and non-fighting, fighting or aggressive behavior may occur if they are kept with other fish. Before selecting and purchasing any ornamental fish, it is best to conduct detailed research and consultation to ensure that they will live peacefully.
