What is the life span for a rosey red feeder fish?

Answer 1

Feeder fish are simply fish that have been "deemed" to be not good enough to keep alive and so are sold as food for other larger fish. They could live a normal life span for their species. Rosey Red is a colour not a species but if you are refering to the Rosey Red Barb then the fish could live for up to 5 years if you do everything right.

Answer 2

It could live as long as 5 years if you look after it properly The minimum standards that all fish must have in order to survive. The basic minima are. :-1 inch of fish needs a minimum of 1 gallon of water. Every tank must have a permanently running 'cycled' filter. Every tank must also have at least 50% of its water replaced every week.
