Today i went out and got a tinfoil barb MD?

The barb is not a fussy eater and once used to the tank would eat pellet foods of any type and any rosy reds small enough to be swallowed whole. Eventually the oscars would kill the tinfoil barb. The barb is such a fast swimmer, it would escape most attempts on it, but the oscars will be relentless. The biggest problem in the tank is that if the oscars eat any of the rosy reds, fish is not in the oscar's natural diet and they can't properly digest and assimilate fish. This can gradually impact on the oscar and cause sudden death with no external signs of a problem. Invertebrates such as crayfish are the main dietary item for oscars when in their natural environment.
