my westerns as with all my animals excluding the redfoots were rescues...the two westerns cam to me cause a lady had bought a 5gal "growout" and then they grew from the size of a quater to 2inch shells in no time and she didnt have money or time for a bigger tank and thought they would do better in the care of someone else ...just so happen to be me and my 55gal...guppies you can just get 2 males and 5females from you lfs and stick em in a 10-20gal and wait like a month then youll have a nice supply...
