I found 2 Assasin snails in a 29g I was cleaning the other day after at least 6 months of not seeing any. I would like to find out what their needs are so that they will thrive and multiply. My 29 was survivable, but not good for prospering, unlike the ramshorn and pond snails that I had tried to control with the assassins. One of the assassins had a severely degraded shell; it was amazing that it was alive.
Any info on how to keep these facinating little guys going.
