well there are ridgetail monitors which are goannas and they are about 60cm long but they are a red and cirular patterns all over their body. then there are gilleni which are smaller about 45 cm and they are a grey/brown colour. there are also black head monitors, there are 2 types a bigger one and a smaller one about 60-80cm long, they have a black head and tail with a spotted pattern on their body. nothing really looks like a lacey but a lacey but there are plenty of smaller goannas they are awesome.
i have 4 ackies and they are great. best small monitor to start out with.
