This is a very good pointGood luck getting a non-snail eater to eat other pests…
The best way to do that is through getting snails that are either Nocturnal or can flip themselves.
The downside to pinkies is;
1. They’re a nightmare to get unless you’re looking for them in the season’s they’re available
2. They only eat the smaller pests, if you have huge Flatworms/Nudibranchs you will want to get a different species of wrasse.
