Maybe it's Zoey's massive mouth and urge to rip my hand off? xD It just takes a lot of patience to tame them. Unless you can sit there moving your hand a millimeter a minute towards them, they are gonna want to bite the first few(many) times, lol.
For Cresties it's about 8 bucks a month for food. They eat a little nutritious smoothie you make them, and depending on if they are separated or not, you can poor half for one, half for the other, etc. If they are in the same tank, they eat from the same bowl so you don't have to split the food =P By far the easiest to take care of. 2 bucks a week for bottled water(misting + water dish), too. I don't use tap water. All they really need is an under tank heater OR a red infrared light for heat. One or the other, I don't use both(they don't need as much warmth as other reptiles). The initial cost is more expensive than a leo, but well worth it. I think they are more enjoyable than leos because they jump. The other day I opened the cage before beardie bedtime and held my hand out to her, and Lily jumped right onto my face. I heard a big *splat* before I even knew what happened, lol. Was so cute xD
The Leo smile is enough to get you though, haha. They're very curious(as are cresties) and when they're looking around while they're hunting or scouting, they make the cutest faces. xD It reminds of when a puppy will tilt its head when it hears something funny, or tilt its nose up to the sky when they smell something funny. They have so much personality
Anyway they don't eat a lot(I mean compared to beardies) You can buy a little tub of mealworms and it will last a while(a 500ct. tub of mealies has lasted me two months so far, but i only started feeding them to leos a week ago. I've used only about 50 for them?
). Just keep a bowl, that they can't get out of, in their cage and they will eat when they are hungry. You can drop a few crickets in with them occasionally, too. I have to have a red light AND under tank heater for them. It's really hard to get their temps perfect. x.x Plus they need a lot of hides, while cresties need plants and things(and space) to climb. 2+ hides is recommended(one for hot side, one for cool) but more is always better. I have 4 hides in a 20gallon tank.
Both are extremely friendly..I know HOW to piss off both, but even when they are ticked they can't hurt a thing(except a fly, perhaps). Leos make angry squeaking noises when you scare them. Like a little leo growl. A ticked crestie will open its mouth, but will only bite if you tick it off even more(which is hard).
I could have a house full of cresties or a house full of leos and I would be equally as happy with either. =) I'll stick with both, though
