Is it safe to keep Oscars and red bellied pacus in the same tank?

The Pacus are vegetarian and pretty harmless but they get very very large weighing in at around 30 Kgs (70lbs approx) when fully grown. Oscars are tiny by comparison. When fully grown they are only about 1.5 Kgs (4 lbs approx). Minimum sized tank for a couple of Oscas is about 72" x 18" x 18 ". You would need a very large tank maybe 10 x the size the Oscars need. Something that holds several thousand gallons of water to keep Pacus successfully.

Could I introduce another Oscar into my tank?

Oscars grow relatively large, aggressive and are messy fish. If there is sufficent room in the tank and the Oscars are of similar size it would be possible. Just feed current Oscar first, turn off the aquarium lights and perhaps rearrange the aquariums decorations as you add the next one. Fish are more passive when full, having the tank dark decreases stress on both fish to make the introduction easier and rearranging the tank decor will sometimes pacify some territorial fish.


How can you keep your tank clean with three Oscars?

The key for that will be strong powerful filtration. Oscars require a tank measuring at least 70 inches (about 180 cm) with a capacity of 100 gallons and up (about 400 liters). Due to its eating habit (messy eater that produces a lot of waste) water changes should perform often and powerful filtration system is essential.

You might be able to get away with it, but honestly i don't think it's a very good idea. The Oscars are likely to nip the fins of the koi. Oscars are much more aggressive
