I have one crested gecko in a vertical, 29 gallon tank. The gecko is 6 inches, head to tail. It eats well and is able to be handled. I have a second crested gecko; about 3.25 inches, head to tail in a separate smaller tank. It also eats well and able to be handled. I had them both out and near each other with neither paying any attention to the other. Am I able to put the smaller one is the 29 gallon too? If so, is there anything I need to do in respect with more areas to hide or two separate water/food dishes?

I wouldn't recommend placing the two together. Did you measure head to TIP of tail? or base? Either way, one is obviously about half the size of the other and may be bullied. Do you know the sex of them yet? As adults, you can introduce male and female or female and female, but not male and male. If you have a male and female, make sure that the female is of the proper breeding age/size, has enough calcium in her diet, and also make sure there is at least one other female in there. Most of the time, if kept together 24/7, males will constantly harass a single female. Adding another female in there will divide his attention among them.

I wouldn't recommend leaving a male/female pair together all the time either. Over breeding and constant egg production takes its toll on the female unless you intend to cool them both for a few months to stop egg production. Year around egg laying can greatly increase a calcium crash.

Two females of nearly equal size can do well together all the time though I would provide separate feed dishes to limit competition for food and make sure there are plenty of plant cover, either artificial or live or combination of both. Visual barriers help avoid stress and competition.

For now, definitely continue to keep them separate till the smaller one catches up in size and you are certain of its sex.

You wouldn't want you to wake up to an injured or even dead gecko,that would be very sad.
