What is slow growing and would survive 6 months - a year in a 100gl. Maybe a 120. But not 100% if I am getting one yet. We are going to build a pond so it would have to be a NY native. Any ideas? The filtration is a 110 filter and a 75 filter, don't know the names off the top of my head. The tank is 18" wide. Temp maxes out at 60 degrees.
