Pond Boss Forums MANAGING AN EXISTING POND Evaluating and adjusting fish populations What is the downside of GSF?

My experience with GSF is they have always been too small to be of any consequence. The largest one I have ever seen was around 6", and DIED's pictures of full grown GSF were astonishing.

I suppose they they were so small because of insufficient predators in those waters. I would like all the diversity possible, but since my pond is a bit small-ish, I will be cautious for now.
