you know tetrapond makes a wheatgerm based spring / fall diet food also...its just a good thing to start the season off with wheatgerm...far more easily digested than regular foods. but they also suggest that feeding is O.K down to 39* with wheatgerm foods. altho i dont know if i agree with that. most folks stop feeding all together at 50*. below that temp they can lightly feed off the pond if necessary. that said, i also ocassionally use that food.
As printed on the above Tetra's instructions, Tetra does recommend ponders to feed fish 2 or 3 times per day when the temperature is at least 50 degrees, and to reduce feeding when temperatures are between 50 & 39, and do not feed at all thereafter.
If the above instructions are Gospel, then I might have starved my "Fire Cracker" to death. For the past Winters/Spring Seasons, I had starved all my fishies as per advices from the fellow ponders here
In retrospect, Fire Cracker was the only fish which had lost lots of weight and died "skinny" during the last Winter/Spring season. In April 2011 when I found Fire Cracker "sat" at the pond floor by the corner, I though it still hibernated, but then I realized it passed away while it was in its sleep. I didn't think it could die of starvation as implied by Tetra (i.e., per Tetra, ponders need to feed fish when the temperture is at least 38 degrees.)
