That's a good deal living that close to the fish food plant.

It might be good advice to cut back on feeding in warm weather, but I would monitor the pond temps. and maybe feed them early in the morning up until the pond temp. reaches 70 then stop until things cool off.
Every pond is different, I feed twice a day all summer but then I have 110 gpm piped in from the stream so that gives them lots of cool oxygenated water.

Keep us updated on your trout growth, I'd like to see more people stock tigers, then they would be hooked.
