Ive had a group of 9 neon tetras for almost a month now, this ones belly is continuously growing and I’m not sure if its eggs or bloating

About a week ago I purchased a couple freshwater plants from a local aquatics store. The store owner informed me of a snail issue he had been having in the tank as he picked a few off the plants. I didn’t mind as I knew they would keep my tank clean and help the ecosystem and cycle. However I have no idea what they are and neither does the store owner. Any ideas?
