Thinking of getting more assassin snails

[newtoshrimps]

I had 2 assassin snails and they died (or were assassined by fish).
In the tank, at the time, I had 2 four inch blind cave tetras. One tetra kept going where the empty assassin snail shell was. I am guessing the tetra ate the assassin snail.
The other snail I found floating in the tank, shell-less. It didn't move when I touch it, so I disposed of it.

Since then I added a shell to add calcium in the tank. I feed a variety of foods to the fish (mostly guppies). The blind cave tetras are gone (returned to fish store because they were too big for the 20 gallon tank (I got them when they were only an inch and was told that they would only reach 2 inches)... Never again getting fish without doing research first... Anyways, my question.

I can't find much info on assassin snails, or the info is contradictory... So can anyone tell me how to keep good care of assissin snails? Or point me in the right direction for reliable information.

I am getting tired of picking out ramshorn snails every time I look into the fish tank (I am easily taking out a dozen a day and there are still more).

assassin snails are pretty easy. If you have other snails they'll eat them. If you don't have other snails, they'll eat sinking fish pellets or whatever else they can find. In my experience they're pretty good at fending for themselves... I'm honestly surprised you lost the first two you had.

Do you need a shell for them ? I just got mine and I don't have any shells..

Um.. They have usually have shells already.

Ok dumb question

The shell in the water is to help put calcium into water. A little calcium leaches off (comes off) shell and helps fish build stronger bones and snails build stronger shells. A fish store employee told me to do it.
It works in shrimp tank too, especially after a shedding and regrowing of exoskeleton.
