They lay their eggs above the waterline so they are easily spotted and easy to remove from the tank if you don't want 50-100 babies running around. If you want more info on your brigs go to www.applesnail.netTommy Gun said:They can breed pretty fast and take over a tank. They are either a male or female and sexing can be done if both snails are the same age since the female will be bigger.
edit...just noticed someone else already posted the link I provided...oops.
