Hmm if they don't get along, it's possible they still won't get along. That's a pretty big space. I would suggest creating many visual barriers within the table (ie. plants, hides, walls). I think that would give you the best chances! Good Luck
If Your Making it 7.5 ft long, i would make it at least 3 to 3.5 ft, so they have lots of space!
once you make it 2.5 ft your gunna wish u made it 3ft or 3.5ft
best with luck tho
Are you positive that you have two females? It's very rare that female Testudo don't co-habitat well. It's very common that males don't or that a male is continually aggressive around a female. Regardless of the gender combination, 2.5' x 7.5' may or may not be large enough. It's going to depend upon how many barriers and hiding places there are within the enclosure and mostly how aggressive the dominant tortoise is.
I just wanted to clarify, I only have one female...I'm just considering a second. Hopefully they will get along (or ignore each other). I just wanted to make sure there was enough space if they don't.
Unfortunately 2.5' x 7.5' is as big as i can manage. Any tips for how I can make the transition from her current home to the new one easier for her?
I've never known two female Russians to not get along. One may very well become dominate over the other, but with females it is usually a very mild dominance and often seasonally related only during breeding and nesting periods. On rare occasion you may run into one that is overly dominate and acts like a male would, but rarely. Males on the other hand are usually a very different story!
