FoggyJ - I've seen SMB survive to sizes of 19" long with a couple HSB for 20 yrs in a small pond with no aeration (despite my pleas) until an algae bloom, and the DO sag killed them one August (due to progresive pond aging and eutrophication). No HBG nor YP died. The pond owner then installed electric aeration. The pond is used as a domestic water source. The pondweeds were kept to less than 20% with grass carp and aquashade. Tree leaf and corn fodder inputs were minimized with fences. Fish received pellet feedings about once or twice a week.
