or mertons water monitors,but even things like thee and spencers,sandys ect,as adults can be a handful,they arent for the faint of heart,id suggest more your ridgeys,tristis ect as a first monitor,but if you wanted something bigger, id lean towards mertons,then spencers,spencers might not have the length of the larger monitors,but they are short tailed and built like a brick sh@t house as adults,so could prove a handful,and you dont want one of the larger ones biting you,some say it doesnt happen,but during a feeding frennzy they can go nuts
