I've Just Found Tadpole Snails In My Axie Tank

I don't know how to get rid of them. All I can think is keeping my axie in a small bucket or something for 4-5 days while I run through a snail rid treatment. I don't know how the snails for in there. There's no live plants and I use a separate bucket for water changes and cleans to my tank that has a snail infestation. I have been so careful...

 

Alright. Ive taken all ornaments out, isolated the feeder fish siphoned out millions of baby snails. All decorations have been hit with boiling water to kill snails /eggs.
