Do your koi move aerator and lights around?

[Bossman]

Surprise suddenly my koi have decided to rearrange my lights and aerator. Have others seen this happen? This was unexpected on
my part. My pond is above ground and bare bottom, just the liner. How can I keep the lights where I put them and not have fish move then around. Any suggestions?

Yes ! They are koi toys! I have my lights taped to 4x4" ceramic tiles. Double the tiles if they still move them. Airstones are weighted with large metal nuts.

Thanks that is a great idea with the tiles.

I use waterfall foam, encase the light to the rock and put it back in the pond.
