I haven't put the fish outside yet though, just some water plants and we'll wait till it's a little warmer to acclimate the fish. It's still in the thirties at night and they're used to inside.
The thing in the birdbath is a runway light lens I stole in college. ;~) Time will tell if the birds will like it there. It catches just a little bit of light and it might scare them.
Oh - I remembered to find the rubber duckie... now my pond is a happy pond. :~)
