do ghost shrimp eat ordinary snails, like apple snails, mystery snails, and turbo snails?
As far as I know, peace species dont eat snails, however there are many species of ghosties and are very hard to distinguish from one to another. It would be horrible if you have got those aggresive species, they carnivore and will likely to eat your fishes and even your snails.
How do you identify the 'peace' species from the carnivorous ones?
I was at pet smart today and they had ghost shrimp in a tank of snails and all the snails where dead and they seemed to be aggressive towards theirs shells.
Short answer, most Ghost shrimp don't go for live snails or fish. They will pick algae and other stuff off their shells, but not harm them in any way.
But, best to ask at the store what species the shrimp are. When the store gets them, the species should be listed, so they should be able to look it up if they don't know offhand.
The most common 'Ghost' shrimp is the American one.. Paleamonetes. It's peaceful, won't harm fish or other inverts, though it will eat baby shrimp of any species if it can catch one. Once babies get a bit of size, they won't bother them any more. Almost all shrimp eat dead things, of any kind. Fish, snail, clam, shrimp, doesn't matter.
But most of the really aggressive shrimp are members of the Machrobrachium family. Not all of them are nasty, but a lot of them are. When they are young it can be hard to tell them apart from other shrimp, but when they get a bit older, it's easy. They'll have longer front legs, much larger front claws, and often a much darker coloration. Some of them are really pretty, in fact, but can't be kept with anything other than their own kind and only if there is enough space.
The only Machro species I've kept that was peaceful was Blue Claw Whisker, aka Indian Whisker.. they were very much like American Ghosts, but a wee bit larger and the front claws, [also larger than Ghosts] were light blue. The colour is hard to see on some backgrounds, but it's blue, for sure. They will also eat babies if they catch one, but are no better at catching them than American Chosts are.
no they eat algae and brine shrimp, theyre too small to eat snails
