Hi i just bought a green bottle blue along with a chilean rose today, they are my first T's. The rose is a subadult but i dont know how to sex it? The green bottle blue is small like an inch long? When can i sex the blue bottle green and how lnog do they live for? I bought it for 40$ was that a good price? Also when you measure ur t's is it the leg span going side to side or head to abdomen?
