Currently have a 30 gallon tank setup with 9 Black Neon Tetra and 10 Neon Tetra. I added 3 assassin snails back in December to the tank to help with pond snail control. Even with manual removal, I still have quite a few pond snails. I have been told to add a couple of loaches to counter the snails, however, after spending the money on assassin snails, I'm afraid that the loaches will eat them too.
Would it be wise to remove the Assassin snails from the tank (sell or trade them) before adding loaches to the tank?
