Sudden infestation

I just sat watching my tank this evening and noticed hundreds of snails in the substrate. I am tryingbto put up a video but it looks like a moving carpet. Nothing added to the tank in the last 6 months. How do i get rid of this. It wasnt there earlier when i did a water change. I would have noticed.

No sign of anything in substrate today. No idea whats going on. Baffled. They are surfacing at feeding time. Whatever they are they are in the substrate.

Add 2 assasin snails, they'll make sort work of them over 2-3 weeks and clear it up. Other choice using a sort of snail trap is add some weight down veg like cucumber, snails go mad for it, simply remove the food and the snails with it and repeat

Was thinking assassin snails but these things bury themselves till food goes in. Will give them a go. Thanks

Assasins will hunt below the substrate, actually you'll find the assasins go below substrate after they've had a big meal to digest it as I've noticed

Didnt know that. Last ones i had were allways on the glass chasing little snails. These ones are different to the usual problem. I will be in seahorse the weekend and get some. Thanks

Get yourself a pack of YoYo loaches, after a couple of days you will never see another snail in your tank. They love to devour snails.
