When you go to the bait store and you see those HUGE 10inch Tiger Sally still in larvae stage. If I were to bring some home to put into aquaria, how do I maintain them so that it will remain larvae ? or ... is it up to the salamander itself ? It's really weird to see those 3 inch terresterial stage and yet alot of 10inch animals still in larvae with HUGE gills , it's very impressive. What are the elements to consider that make an individual salamander turn terrestrial stage and another doesn't ? Again, is this just an indivdual decision or are there certain elements in the water or environment? I've noticed even some axolotls turn terrestrial as well........
