Good morning,\nI am new to the forum. Been ponding for several years now. Started with just a little puddle and one carnival gold fish. When he survived the first winter my daughter dubbed him "Miracle Fish" and we were hooked. My LAST expansion I made the mistake of doing it while my husband had his backhoe nearby. Now my liner is about 20' by 18' and about 32" deep. We now have 22 fairly large gold fish and every year we have about 20 babies that we have found new homes. I'm looking forward to learning SO much for all these experienced posters.
