Red Oscar by LiveAquaria
The Red Oscar is a color variation of Astronotus ocellatus, also known as the Marble Cichlid or Velvet Cichlid. It is a vibrant addition to a large aquarium, featuring an orange-red body with dark gray shading and an eyespot on the dorsal fin.
Red Oscars naturally form pairs and establish a nuclear family structure. They are generally peaceful and thrive in a well-established environment. Male and female individuals are difficult to distinguish, though the female develops a visible genital papilla during spawning.

The Red Oscar adds a striking color to my 100-gallon tank. It pairs well with other cichlids and is very active without being aggressive. I’ve had it for six months and it’s still healthy and curious.

Beautiful fish with a unique appearance. It forms a pair with another Oscar and they seem to get along. I had to adjust plant placement to avoid root damage, but it’s manageable.

Great for larger aquariums. The fish is calm and active, and the eyespot on its back is very noticeable. I appreciate how it doesn’t stress other tank mates.
