RES should eat the immature trap door snails. Once the snails grow to over 1/2" long, I think they are in a size refuge regarding RES predation. I've never dealt directly with trap door snails and don't want to. It is my understanding they are a nuisance and considered invasive, however as a positive, they eat attached algae.
