Have a few assassin snails in my nano, was thinking of putting in a Ramshorn from the big tank (some hitched on some plants, a few turned out to be a bright pink/orange, the rest black). Will the Assassins make him lunch? They leave them alone in the big tank but there are plenty of little pond type snails in there for them to chop on.
Thought about getting a nerite or 2 to eat algae, but heard they leave hard unsightly eggs everywhere.
Thinking that my MTS were safe from Assassins I put a couple of the latter in one of my shrimp tanks. I'd raised the sweet MTS from babyhood, have had them for years in an old 10 gallon tank with nothing else. Anyway a few minutes after putting the Assassins in the tank they attacked one of the MTS's. I freaked.
I bought the Assassins to get the pond snails that caught a ride on a plant.
The Assassins found a new home real quick, by the way!
My assassins, when they can be bothered to hunt will happily take down a full sized ramshorn or MTS, pond snails they seem to avoid though. Bear in mind that my assassins are fairly lazy though, and I have read about other peoples eating pond snails happily.
