I'm At A Loss. My Small Goldfish Are Disappearing And I Can't Find The Answer?

[holmesr]

I've lost 7-9 fish in a small backyard pond (under a deck) in less than 2 weeks?

Sharks?

[jno]

anything to stop cats or birds getting at them?

[CrapAtCryptics]

Any frogs around they will eat anything they can swallow.

Herons often take fish from garden ponds. Netting over the pond could be a solution.

What can get under a deck ? A cat maybe ?
(Unless you added a piranha recently.)

[rowanwitch]

Rats, foxes, crows and magpies surprisingly enough magpies just can't resist small shiny things. Net it or set up a trail camera....

[woofgang]

do you mean under a deck? surely it would be very dark under there?....or do you mean its on a deck under a roof?

[johnny.5]

being eaten by the bigger fish

Well here in our village we have an otter that has emptied just about every flaming pond. It came last year and we re-stocked but it's been back and our pond is now empty once again. It's been clearly seen on neighbours video night camera, beautiful creature, but poor old fish:-((
