When you list "three-horned" I'm not sure what species you are talking about...Jackson's? Usambara three horned or deremensis?

Both of those species will need a much more humid setup and cooler temps with significant night time temp drop and very careful supplementation (montane species are much more sensitive to oversupplementation). If the climate in your area is dry or hot in summer that could be harder to deal with. For a beginner as you describe yourself I'd suggest the panther rather than the others.
