Feeding a betta and a snail together

[folklor]

Hi there,
I just got some sinking wafers for my assassin snails since I'm running low on pest snails.
I dropped a wafer in, and it sank without my fish noticing - or so I thought. But when I checked later, my fish was super swollen with no wafer in sight. I'm planning to fast him for now and maybe feed him a pea in a day or two if needed.
My main issue is figuring out how to feed my assassin snails without my fish finding the wafer. They're nocturnal, so they hide in the sand during the day. I can't just put the food right in front of them.
Any advice would be great, thanks!

Try feeding the snails at night, after fin_tank has settled in for the evening.
