Just seen some of these guys. I have plenty of experiance with MTS(Malaysian Trumpet snails) and the fact they do a great job. However, not much experiance with Assassins. Do they bother live plants? Do they work the gravel as well as MTS? I have an option for either or, but I think their black color would look better with my gravel. Also, do they stay under the gravel as much as the MTS as this guy claims? Thanks for any info you gusy can provide.
