>>geez no need to get smart dude just looking for an opinion
You didn't seem to be listening to my first response, so I thought it didn't matter what I said.
As a beginner, you may have ambitious plans. "I'll start with something small and then get a larger setup." This happens a lot. A leopard or red foot would require a much larger setup as they mature, and you may find that you can't really handle it in a couple years as it approaches mature size.
I think a mature leopard or redfoot would require more like 20 sq ft. These are animals that get at least 12" (shell length).
Much more room than needed for a box turtle or russian tortoise.
That's why I recommended something that could actually live its entire life in the 30 gallon tank that you now have. A mud turtle is interesting, active, and relatively easy to take care of, once you have a handle on water quality issues.
I suggest starting simple. Don't get overly ambitious. If you find that you really like taking care of a turtle, you can move up to something more demanding.
I started with small lizards, but tried too soon to get a tortoise. I lived in an apartment and couldn't provide a spacious setup. I had to sell the tortoise (a red foot). Now that I have my own house, I have the room to create both indoor and outdoor enclosures. I also find it easier to do so for a 3-toed box turtle, since they are native to the area. My russian tortoises take more effort since the local weather is often too damp and cold forthem.
Best of luck whatever you do.
