I am new to the fish keeping thing and just had my tank set up. However, the plants I used seem to have been housing snail eggs and my tank fish is now invaded. So, I wanna ask what kind of snails they are ( I have included some pics) . Also, how should I deal with them? I have tried immersing a water bottle with lettuce into my fish tank to trap them but didn't even catch a single one for a whole day.
