They are either having sex (male and female) or they are just playing around.
No but baby beardies have been known to bite each other's tail off by accident in play
Make them get along- feed them both treats when they are near each other. If they attack each other ferociously, separate them into different cages of give one away.
NO ! They would NEVER encounter each other in their natural habitat - and should NEVER be housed together in captivity !
Depends on where you are buying them from. A good price is around 30 dollars each.
No ! They need completely contrasting living conditions ! Bearded Dragons need dry, arid conditions, Frilled Dragons need a humid environment. They would never encounter each other in their natural habitats - therefore should never be housed together !
Yes, its very common so keep them separated until they are used to each other. Do this buy taking them both out regularly but separately. After they both recognize you as a friend then take them out together but one in each hand and if one of their beards get black, put them BOTH away and try again the next day
NO ! They require completely different living conditions, temperatures and humidity ! NEVER mix species unless they would encounter each other naturally !
No a bearded dragon cannot each sugar. If you were to feed them sugar it would instantly suffer from either an illness or even a slow death. I do not advise you to try this!
Of course! Bearded Dragons are naturally calm, friendly, and kind! They can look a little scary to a baby, but if you get them used to each other, they'll get along together just fine! Of course, you should keep your beardy in a tank, for their safety.
None ! They are (like most reptiles) solitary creatures. In their natural environment - they would only seek each other out to reproduce. If you must keep more than one Bearded dragon together - make sure it's either a pair (male & female) or a 'harem' (one male to a number of females). If you keep more than one male together in the same enclosure, they will fight for dominance.
The most probable answer will be a no. Be more specific with what species of gecko, or what species of chameleon as there is multiple species of both animals that range from different parts of the world.
Dragons are mythical creatures. Depending on different authors and directors, dragons and other mythical creatures are always different. Okay obviously that isn't a helpful answer, so I will move it to bearded dragons for you.
