I have brought 4 Tiger Oscars from a local fish store.I keep them in a 300 Gallons tank with 2 Cat fishes,1 Giant Gourami and 1 Snakehead fish.I want to grow my Oscars upto maximum size they grow and I want MFK's help to grow them fast and maximum.
Oscars grow insanely fast with the normal steps of clean water and regular feeding, I'd be more concerned about possible aggression; but I haven't kept a tank that size with that combination, so its just a thought.
This. The catfish, depending on the species, will make a meal of small Oscars. The snakehead is going to be a jerk at one point or another.
Go for a really high quality pellet, as your staple; lots of different brands are recommended on here; such as NLS etc. Then you can work around that and try vegetables, and/or frozen foods, prawns, bloodworm etc.
they are your fish lol, I would say yes, but you do what you want. Give them a good pellet as a staple diet, as much as they can eat a day, and water changes. They'll grow.
