Re: Question About Golden Apple Snail
It isn't legal to sell canalculata in the aquarium trade anymore, so you shouldn't have any problem with this snail and most live plants. I've had Pomacea bridgesii/diffusas in my heavily planted tanks for years and have no problems with them eating live plants.
If you can get me a picture of him straight on so we can see the angle between the angle of the whorls a bit more clearly we can confirm the species identification. Bridgesii/diffusas have a nearly 90 degree angle where the whorls meet, a canalculata will have a more oblique angle (greater than 90 degrees). If you have a canalculata you should probably return it to the store, but I'm pretty sure anyplace but Walmart is pretty safe on their snails. (People on Applesnail.net have caught Walmart selling canalculatas a couple times. &^%$# Walmart.)
The algae on your snail shell (the green) is no big problem. It is algae. If there was another snail, that snail would scrub off the algae, but since this snail can't reach it, it can't eat its own algae, so maybe the fish will pick it off. But it won't hurt the snail or its shell.
The crack could be a bigger problem, but as long as the snail has a good diet and enough calcium the crack will heal. Probably just rough handling during transit. You can add a cuttle bone like people give birds, or a weekend feeder, the kind that are made of plaster mostly, those are also a good source of calcium, or your clam or oyster shells from when you go out for seafood. The snail will like to eat bottom feeder disks, canned spinach, partly cooked carrots, zucchini, things like that, but only a little at a time. Don't give it more than it can eat in a couple minutes or you'll end up with fouled water. The fish will probably like these treats as well.
Some people who have access to empty snail shells will cut a little snail shell off and super glue the shell over the crack as kind of a cast, but unless you have exposed tissues that the fish are picking at, it is unlikely to be necessary. Applesnail.net is a great place to get more information on your snail.
