Hi this is the 2nd winter ive brought my pleco in for the winter, hes grown since last winter and hes in a 30 gallon, what im asking is , will that be ok just for the winter mos. then hes going back in pond. Hes maybe 10 inches in length. Also how long should i wait before i feed him , how long till he adjusts to the water temp change, the pond was 50 and the aquarium is about 72. Any help will be appreciated, thank you
