Oscar fish can be a great tank mate of flowerhorn. The South African Oscar fish is called a water dog. It means they become very intelligent and know their owners very well. Flowerhorn is intelligent too. So they can become a tank mate of each other if they are taken care of properly. 

However, flowerhorn is a highly aggressive and high-tempered fish. So you need to keep your eyes on both of them. Oscar fish can survive without food for fifteen to twenty days. On the other hand, the flowerhorn needs food many times a day. That’s why flowerhorn is called the hungriest fish. For these two fish, you have to choose a heavy diet so that they can survive for a long time.

Flowerhorns grow faster than Oscar fish. These two fish are large so it is very important to have a very large tank for them (at least 4ft). Both of them are warm water fish. They should be kept in water at a temperature of at least 26°C to 30°C. Oscar fish and flowerhorn are both omnivores. 

Too much decoration inside the aquarium isn’t good for flowerhorn and Oscar both. They may destroy it. So it is better to keep them in a normal aquarium. 

These two types of fish are aggressive, so if someone wants to keep both of them in the same tank, then they should be brought from a very young age. Moreover, the two fish must be of the opposite sex. This is the only way to keep these two fish in the same tank.

Since they are both quite large, keeping these two types of fish together requires a large tank that holds at least 150 gallons of water. They like to live in clean water. They like to live in clean water, the water filter should be of very good quality.

On the other hand, flowerhorn likes to live in little warmer water that is 30°C. Therefore, you can maintain a certain temperature between 22°C to 30°C of the tank that carries jaguar cichlid & flowerhorn both.

A good filter should be used and the water should be changed frequently so that the temperature of the water remains perfect for them.

Jaguar cichlid grows up to 24 inches long whereas flowerhorn grows up to 13 to 16 inches in length. To keep these huge fish in the same tank a minimum of 170-gallon is required. Otherwise, they will not freely move around in the aquarium and they will start fighting with each other.

The change in the appearance of this fish with age is very interesting. The head of this fish is flat when juvenile but with age, the lips become wider and the head becomes quite swollen with a thick chest.
