I've got an old belfast sink next to my pond which i stick frogspawn in, the fish eat everything in the main pond.
Noticed last night the all the tadpoles had gone... Then whilst rooting about i found a smooth newt (the first time these have appeared! and the suspected culprit), a frog and a toad all living in the same sink! Almost all the UK's amphibian species living in one 1' by 2' sink!
Brilliant...pics please. :)
