I don't know if the gar are killing them and not being able to eat them because they are to big or if they are just dieing?
Were it me,(and it ain't) I wouls stop with the feeder goldfish and guppies.
I would try offering foods such as frozen chopped fish,shrimp, Krill,earthworms,and vegetable matter as well.
Far less danger of introducing disease to the tank.
Would offer these foods and take care to remove uneaten portions within an hour after fish have fed ,lest water quality issues arise.
May have to let fish go hungry for two or three days to interest them in the new foods if they have been eating live foods, but they will be far healthier in the long run in my opinion.
Google diet info on the fishes you have and provide accordingly.
Service the filter more often and see if it doesn't help with water cloudinesss and as mentioned,,try not to perform large water changes if at all during boil orders. Good luck.
