I hear you speak of these all the time, but I can never find them. I'd like to get some for my sand bottom tanks. Where should I look?
you can sometimes find them at a petstore, and if you get a fish or plant, they'll usually just throw the snails in the bag for free if you ask. you can also usually find them on aquabid.
My pet store has them. I don't like them though cause they multipy to fast, unless I have somthing different.
you may have something different, MTSs are livebearers so they dont leave eggs and reproduce more slowly.
this is one of the types of more common snails that tend to reproduce very quickly, and tend to serve little purpose in aquariums. their shells tend to be somewhat translucent, and fairly brittle, so if you put a finger on them, they can be crushed with little effort. on the other hand, MTSs have one of the hardier shells, so much so that clown loaches dont crunch them, but rather suck out the bodies.
this is a malaysian trumpet snail, the colors of their shells can vary a little bit as well.
would rays seek them out as food?
im not too sure about rays eating the snails, but a couple of clown loaches will take care of the snail population quickly. another way to deal with an overabundance of snails is to soak a lettuce leaf in hot water, then place it in the tank just before turning out the lights for the night. after a few hours, or the next morning, there should be a ton of snails on the leaf, and you can just pull it out and do with them as you please.
