I think it depends on species and temperature. I'd guess anywhere from a week to a month.
Snails hatch, grow- live, reproduce and die at a faster rate the higher the temperature. Temperature accelerates their lives.
I imagine the Ottos will dominate who gets food first and control the snail population rather than the other way around... but I really don't know. Are you supplementing the Ottos with other veggies?
Time for the experts to step in and answer that question though. I don't think your Ottos are going to be outcompeted but I am an expert at nothing...
