What is the likelyhood of salamanders/newts escaping from a tank given that it has a standard hood with minimal openings? I know that inverts can find ways and such, but would salamanders slip through something that is maybe less than 1 cm wide? Would they have the desire and ambition to leave the confines of the water and crawl up up and away or are they not the explorer type? (fire belly newt and similarly-sized amphibeans are what I'm refering to)
