Oh, I am sure that 'he' is no where the size of yours. Last I saw him he was about 12" but they grow over the winter even though dormant. I figure he is at least 14" now. Haven't see the little guys yet. They were mostly gold fish with one or two Shibunkin. I think about 15 went into winter. No idea how many of those survived. I added Medzyme and Arctic Blend bacteria today. They both can work in 40F water.
