Thanks everybody. I agree that this site is the best place to get information, which is why I posted my question here

my basking spot is above the tank so only filling the tank half way is no go, however, I can take a few more inches out, and I will also put some more large rocks in there and another platform right in the middle for them to rest on. I take what I read on Youtube with a grain of salt, cause I know here is the real place to learn, and I have.
Marisa, my reason for two is because they are really young. I am hoping they will grow and be-friend each other. The tank is plenty large for the both of them and I will feed separately etc.. I am also secretely looking for an excuse to buy a lager tank 120+ so if they do start to get fiesty I will use that as an excuse to the wifey hahahahaha.
