No, they are harmless
Bearded Dragons usually attain full size in 3-4 years. Obviously this depends on how much food they eat, and how often - as this will vary with each reptile.
A fully-grown Bearded Dragon CAN be as much as 14 inches nose-to-tail. It's rare for them to get to that size though - the 'norm' is around ten inches.
Komodo dragons are fascinating creatures and they can grow to weigh 300 pounds or more. In terms of length a fully grown adult can grow to 3 meters which is about 10 feet.
The average adult bearded dragon gets 18 inches long (1 1/2 feet) . There are different species of bearded dragon that can get up to 24 inches (2 feet). I have 5 adult dragons. The smallest is about 14 inches, the largest is about 22 inches. Ones that have some "German Giant" genes tend to get larger but you really can't tell until they are full grown. 18 inches is a good estimate but it could be 4 - 6 inches difference in either direction.
Your bearded dragon will become fully grown regardless of the size of the enclosure, provided you properly meet its needs for food, UVB, heat, and hides, but a MINIMUM of a 60 gallon sized tank would be recommended for the adult lizard to be free of stress and have enough room to be comfortable. Bigger is, of course, better.
They do it to show aggression or the readiness to mate
