We have millions of snails outside. I don't think it is possible to keep on top of them. I tried beer traps before but they quickly became stinking pits of snails/slug death with no sign of affecting their numbers!
I am genuinely not sure how the buggers got in. If they are cool water snails it will be quite good. If something else they are getting gone.
I don't think fish are worth it, no one tells you about all the cleaning and madness that is associated with keeping them healthy!
We have enough to do with chickens and cats. Both give more back than fish.
I heartily agree. I love my cats but feel absolutely zilch for the fish. When the first lot died I suggested getting something else furry instead but oh no, more damn fish
