So I go to the LFS today to get help with a few problems. I'm having an algae problem and I was asking if that was the cause of problems I'm having with my plants. I've noticed that I occasionally get a hole in the middle of a leaf. The clerk tells me something is eating it, probably the gazillion MTS I have. I thought they were good for planted tanks and that they don't eat plants. So I come here and search the forums for info and come across several posts stating that snails only get out of had when you overfeed. I know I overfed in the past. So now I'm a bit confused. Are MTS plant eaters or not? Did overfeeding cause a population explosion that eats my plants now that I'm no longer overfeeding the fish?
