So the snails think they're on holiday? Lol what an image - a snail resort.
And the assassins aren't eating them? Yikes.
I know there are ways to trap snails - try Dr. Google.
Regarding your picky eater who can't eat NLS you could always use a rolling pin to crush the pellets.
I have a very picky eater who was raised exclusively on daphnia - he didn't know what pellets were. The NLS pellets were too big for him too. He didn't care for them even when crushed.
What worked - and what he LOVES - are the tiny pellets in Dr. Bassleer's Bio Fish Food. You've probably heard of it in the UK.
I'm feeding Acai (great for color) but Cavar is designed for picky Bettas (and breeding Bettas) I tried this product - Lo and behold it became his GO TO. To my amazement he prefers this stuff to live daphnia - how that's even possible I don't know?
The cost is similar to NLS (Cavar is a little more) but the protien (from fish) is almost 60% which is double NLS. The pellets are tiny - they float for a bit then slowly sink. My betta also prefers to chase them when they're sinking and he also likes to pick them off the bottom. Nothing is wasted.
I can post the ingredients if you'd like.
Maybe worth a try - if you have similar results, that would cut the snails off from their all you can eat buffet heh heh.
Also it's funny your betta won't chase down daphnia? When Rigel AKA Sparky is fasted he enjoys the sport, but now that he's hooked on this Bassleer stuff he's not so interested in hunting - maybe it's making him lazy? Here's his pic the Acai really brought out his color.
