Im getting a certain kind of cichlid at petsmart (pic included) to put with my tiger oscar?

Question

will he eat the same diet i have my oscar on? (cichlid pellets and flakes)

Answer 1

Nothing about the fish you selected makes it even slightly compatible with Oscars.  P. demasoni needs a MUCH higher pH than the Oscar, is FAR more aggressive, and will need a VERY different diet.  P. demasoni are indigenous to African Rift Lakes where the pH is around 8.5 and the water VERY hard.  Oscars are from South American streams where the pH is around 6.0-7.0 with VERY soft water.  P. demasoni will shred the Oscar in days-- Oscars aren't aggressive, just large and hungry!  Oscars are carnivorous and require a high protein diet.  The Mbuna you selected is almost entirely reliant on vegetable material, which is extremely low in protein-- giving it the same food as the Oscar will result in severe constipation.
