also contemplating snails of a larger variety… a little looking, and it seems Japanese trapdoor snails would likely tolerate the over wintering temps in the upper 50’s just thinking about some sort of clean up crew / fuller environment, in the tank… I’d suspect that pest snails will come, and likely at some point be food for the sunfish, also, maybe glass shrimp???
so maybe hold off on the bigger snails, expecting the pest snails, and hoping at some point the sunfish and bullhead eat them… certainly not going to stock them initially, but if the fish end up eating them eventually I may begin to trap them from some of my live bearer tanks, and adding them to this tank later???
