I have a 29 gallon heavily planted tank that I have about 60+ young Assassins crawling around in. It used to be you threw in 6 green beans and with in minutes they were little MTS logs. Now I have been throwing in large Rams to help feed the adults and I can see their shells but I haven't seen any MTS shells. So I threw in 6 beans as usual since I only do it once a week and they are still there this morning. Guess I need to go snail collecting in my other tanks....
