I try to never put my hands in. Haha. But when i do i dont wash my hands because im scared soap will find its way in my tank. When you guys wash your hands you guys use soap?
And they will find a way out/in. I put in a breeding box in my 20gal and found a crs in it the next day. Only way it could have gone in there is it climbed out of the water.... Wierd.
