What's For Dinner: Obtain from the hatchery food to feed the Brook Trout. Be sure to ask how much to feed to how many fish once they are swimming up looking for food. Development of eggs will vary, just as siblings have distinct traits and develop differently in a human family. Wait until all of the egg sacs have been absorbed and all fry are swimming up into the water column before feeding. Try feeding only a pinch of food at the first feeding. No food should reach the bottom of the aquarium. The fish feed on sight of food in the water column; they will not scavenge off the tank bottom or cobbles.
Remember, food at the bottom of the tank only dirties the tank, and excess food promotes gill disease.
