Mr Aqui enjoyed an afternoon of attempting to drown snails yesterday (it's a bit like having a young son sometimes!) ;D Whilst doing so he spotted a new aquatic life in the pond...
A small (maybe 1-1.5cm long) fairly round black thing that looked like a bit like a beetle. it whizzed about under the water and would occassionally surface, before diving back down again.
what could it be? friend or foe?
