I have MTS in my 20g with sand substrate to keep the sand turning over...they are great and I seldom see them on plants but see the babies on the sides of my tank on occasion...usually I see just a few digging furrows in the sand before going under the sand.anybody keep mts in their planted tanks i know they do alot of good and allegedly wont ravage my plants but will they breed to problematic numbers or be a nuscence
thanks
