Small Pond

[ihasanzongi]

my and dad and i are planning on making a goldfish pond in our back yard, it wont be very big we are thinking around 3fX5f.. i was wonding how to filer this and would i need a heater with this?
im not sure on what type of goldfish, maybe large feeders? all ideas would help. We live in southern Canada so the fish would come inside for the winters..into our spare bath tub..wait till my mom finds that part out

for those feeder fish (commons comets) no need for a heater. A fountain filter or any pond filter will do, just have to skim the leaves out when they fall in etc. 3x5 isnt really big for a pond, probably fit 2-3max of them
