I have a Female B.Smithi which is around 3 years old now. I wonder when this specie becomes mature. I know feeding,heat and the tarantula itself may change the time but i am asking in average.And how long do they become when they are mature ? On average again. I heard that thay will keep growing by every molt until they die .Is it true or after some size the grow is so small that it's not noticable between 2 molts ?
