my plec is going to get too big for my 40 gal within a year or so...its about 5 inches now...i have a outdoor pond with various goldies...would it be able to winter in a outdoor pond?
Pleco's can't hiberate like a lot of goldfish can when the temps drop very low- if they drop too low in a pond the pleco will die, like Tolak said you will need to heat the pond (which can be very expensive) if you want to keep it in the pond all year round.
