I have a question for everyone. My husband and i recently acquired a 55 gallon freshwater tank. We filled it up and put feeder fish in to make sure that the "real" fish we wanted in there would live. So we went to the local trout farm and bought two 8 inch or so brook trout. We wanted rainbow, because of their higher tolerances to stress, but they didn't have any. Regardless, we've had them for 3 days now, and they won't eat anything. We've tried the almost everything we can think of. Does anyone know why they won't eat?
