I picked up some bleeding heart tetras last week and I noticed these tiny snails in the tank with them. I asked the girl what they were but she didn't know, and I didn't care I just knew I wanted them. She ended up just throwing about ten in the bag with the tetras. I didn't really think about them untill just recently, and now I'm obsessed. I need to know the name of them and I can't find anything on the internet. They kinda look like tiny apple snails, less than the size of your pinky nail, kinda yellowish brown in colour, and they are commonly used as puffer food (thats all the girl knew about them). I tried to take a pic but none of them came out well enough too see anything of significance. Can anyone help me Identify them please?
