Other large, aggressive cichlids and fish such as Pacus and Jack Dempseys. Size and temperaments should be kept closely the same. Odd number of fish generally do better to help displace aggression. Tank should also be large enough to house these fish properly with enough territories. When adding new fish to an aggressive tank, feed tank fish first before releasing new fish. Also, turning aquarium lights off for the release also helps. The first few seconds of the fish entering the tank and swimming downward that are the most crucial.
It's easier to say they are good community fish that are compatible with most normal tropical fish. They are not compatible with fish that need special water conditions like Discus or African Cichlids. They are also not suitable to be mixed with large predators like Oscars or Arowanas who would hunt and eat them.
yes
Oscars are cichlids! They are from the South American group of cichlids. Fish can mate only within the same species. Oscars can only mate with other Oscars.
An Oscar is of the cichlid family, the piranha belongs to the characin branch. Otherwise known to freshwater aquarium owners as the bothersome "fin-nippers" which is what characins are known for, along with the skittish hyper behavior.
Oscars when they get big can eat feeders and most types of cichlids will also.
Oscars should be kept alone so they don't eat any of your other fish of fight with other Oscars. Oscars also grow very fast and as they do they become more and more aggressive. They can sometimes be kept with a large plecostomus if your tank has plenty of room.
Well....yes, you can. But I wouldn't expect to find your other fish in the morning. Your oscar will likely eat them.
Oscars (the fish) are supposed to eat goldfish, but they probably have a fish food for them on the market.
tetras, and other non-aggresive fish
Oscars are the breed of fish that mate the most. However, guppies and trigger fish also mate much more than other breeds of fish.
swordtails
Tiger Oscars really should only be kept with Tiger Oscars. if you can find a fish that can grow to be equally large and have the temperament to survive with an Oscar then by all means try to keep them together, but Oscars will eat anything.
