I have a bag of fish food that I bought from Tractor Supply, but I just use it to to watch the fish in the older LMB pond (not used every day). I am hoping that I can get a good food chain going, but if it takes an extra year to get the forage population built up in the new pond, I am OK with that. I will be planting water lilies and want then to get established before adding crayfish, so it may take a little longer anyway.
