    Hey everyone,

    Not the best pic, i can get you guys some more later, but if you look you can see a snail on the plant to the left of the tape measure:




    I'm thinking that this is a pond snail, and I'm thinking they hitched into my 40B with my plants. At first there were only a few, and I really didn't mind...now there are ALOT of them, and Lauren's young eyes are spotting tiny baby ones every day. So I am considering getting some assassin snails to help clean these pests up, but I have a few questions. I have read around on the 'net a bit, but you guys always have the best info, so here goes:

    1. For a 40 gallon breeder, how many assassins would I need to do the job?
    2. I have read that they attack and eat only snails that are smaller than them, true or not? I'd rather my 2 mystery snails not be harmed
    3. When they eat a snail, what happens to the shell? Do they crunch through that too, are do you net out the empty shells?
    4. Since they burrow in the sand, do they provide any aeration benefit for the substrate?
    5. One thing I read on the net was that they occasionally attack and eat shrimp, any truth to that?
    6. Do assassins breed readily in a tank, or is what you buy is all you'll ever have?

    Any other info you guys can provide is greatly appreciated. My LFS only keeps mystery or apples, so if I decide to get some assassins, I'll have to order online.

    1. For a 40 gallon breeder, how many assassins would I need to do the job? Start with 4-5 if you have a bunch of snails in the tank
    2. I have read that they attack and eat only snails that are smaller than them, true or not? I'd rather my 2 mystery snails not be harmed If starving the can gang up on large snails, but its rare that they can take a huge snail down
    3. When they eat a snail, what happens to the shell? Do they crunch through that too, are do you net them out the empty shells? They stay in the tank, u remove or they will eventually breakdown
    4. Since they burrow in the sand, do they provide any aeration benefit for the substrate? Not nearly as well as trumpet snails, but probably some
    5. One thing I read on the net was that they occasionally attack and eat shrimp, any truth to that? No. I have them with RCS, they will eat a dead shrimp though, but can't catch live ones
    6. Do assassins breed readily in a tank, or what you buy is all you'll ever have? They do breed, but it takes a few months before you can see the babies, and then takes another 6 months before they are a decent size - they grow SLOW

    If you want some let me know, could probably get some down to you for shipping costs once mine get a little bigger

    1) start with 5
    2) it depends, I have heard (not seen) them eating mystery snails
    3) the shell is left usually. It will decompose in the water and add a little extra hardness to it.
    4) yes, just a general amnt.
    5) I have never heard or seen that.
    6) yes they can breed in aquaria... see Brhino's tank lol.

    Its hard to control pest snail populations in planted tanks. the long haul answer would be to try the snails out and see how they do on ridding your pond snail problem.

    For sure! I started out with three, because that was all my LFS had. For a while they would eat the pest snails but there weren't enough of them to dent the population. When I upgraded to a larger tank several months later I found a couple babies for the first time. Now... no idea. I'd guess I have at least a hundred of them. You put food down and they swarm out of the substrate.

    yea, don't do that. I could do like $2 each - but its a bit chilly to ship right now. Mine are about half grown and starting to come out, when you look at my substrate closely you see tons of them

    WOW, a hundred?...what food do they go after, I thought they just munched on other snails (?)...your "punk rocker" looks kinda white in those photos, aren't they usually yellow and brown?

    Just to add in my experiences:

    1. For a 40 gallon breeder, how many assassins would I need to do the job?
    Technically this is more of a how patient are you question. More snails will do the job faster, but if you are worried about issues with other tank mates then you could get one or two and let them take their time on your buffet of snails.
    2. I have read that they attack and eat only snails that are smaller than them, true or not? I'd rather my 2 mystery snails not be harmed
    I have not tested this theory. I have had them eat pond snails and a Malaysian trumpet snail that was smaller (came in on plants) and they do like the sinking wafers.
    3. When they eat a snail, what happens to the shell? Do they crunch through that too, are do you net out the empty shells?
    Shells remain in the tank. They stun their prey and then suck the body out of the shell. You can remove the shells or leave them to deteriorate and potentially add calcium to the water column.
    4. Since they burrow in the sand, do they provide any aeration benefit for the substrate?
    Probably some, but I still stir my sand substrate tank.
    5. One thing I read on the net was that they occasionally attack and eat shrimp, any truth to that?
    I have one rather large and healthy Assassin in a tank with a pair of Amano Shrimp and have not seen any shrimp dinner proclivities. I will say that the question on some of the shrimp issues (at least in my opinion) is more a case of how healthy are the shrimp and how well fed already are the snails. If the snails are more starving they are going to look for food. Assassins aren't too picky about the type of edibles wither and will definitely eat a corpse, be it fish or snail. I also keep several kuhli loaches in a tank with assassins and can't say that either hunts the other.
    6. Do assassins breed readily in a tank, or is what you buy is all you'll ever have?
    Assassins are single sex snails. You must have both a mail and a female snail to get babies. They also lay single egg scattered clutches. If you have a male and female they will reproduce. if you just get one, or two and they are both the same gender then they will not. Here's a great photo of what Assassin Eggs look like:




    So overall if you are worried about over breeding or tankmate issues, you could always start with 1 or two and add more if they are too slow for you :)
