Feeding my fish

due to time and colder weather,plus advise from peeps here.
I changed there food to a floating pellet,mysis shrimp, flake food and flathead minnows.
I was unable to keep the brine shrimp alive after 48 hours all attempts failed and I'm now out of green water.
my shiner and 2 chubs eat well but the sunfish will spit out the pellets but he eats most of the rosey reds.
I do have a on going problem with fin rot and white spots in tanks from feeder fish (from Local pet shop)
or local bait house general health and quality of fish from LPS/LBH is poor.
all fish from there die with in days or weeks of purchased.


I would like to say thank you to all that have helped me with keeping my bait fish alive!
also I no longer have a single piece of bait in the house they are now pets!
