A quick update on the outside tanks , Not a great success,
I lost 1 cory and the others did not look to trilled about the temp changes , it was going from 10 -30 degrees every 24 hours so they are back inside and much happier.
The barbs also did not like the changes in temp so dramaticly so they are also back inside.
the danio's the same story so i now have the old WCMM & Leopard fish outside and am thinking what else i might try
