Hi, new member here I'm setting up a new tropical planted tank so I've been buying plants from trade me. Unfortunately, I got more than what I bargained for and I found some snails this morning... They are definitely bladder / pond snails and they are relatively young ( 3 of them had colours and about 3mm long, the rest were still transparent). I've been doing research on them online and I'm getting a lot of mixed opinions about them. Some say they will only eat dead plants while some say it will eat all the plants. And apparently they get out of control but some say it can be controlled by not overfeeding. So I'm just looking for an advice here, should I hunt them down now when it's still just a few and try get rid of it before adding fish or should I just leave them be? What is everyone else's experience with them?
