I have tried about everything. I am sure this has been brought up many times. I know these invading little suckers came with my plants sometime ago. I have heard about certain types of snails eat others does anyone know if there is any type snail that eats others? I thought about yo yo loaches maybe three for a short period of time but they would conflict with my three discus and one Farlowella. Plus two of them are mates and lay eggs often. Any ideas would greatly be appreciated. It is a 55 gallon tank.
