I'm at a loss about controlling my pest snails, there are so many, and trying to remove them as I see them isn't really keeping the population down, as there are still a ton of eggs all over the plants. Here's the issue... standard snail trap won't really work, as I have a ton of baby RCS in the tank. Any hole that would be big enough for the snails, is also big enough for the shrimp. Not overfeeding doesn't really work, as I have to have food in for the other inverts in the tank (so can't just make sure I drop in enough and have it be eaten right away)... Obviously, anything that would cause the snails to die is out, since that would kill everything else in the tank too. Assassin is out, since that could also result in danger to other tank inhabitants. Any ideas?
