I must have done something right! One of them is calling right now. Totally freaking out my cat, which is hilarious.

I tested this morning and the nitrates were up, nitrites were zero and everything else looked good. I got a heater at Walmart because the night time temp dropped too much. My turtle's tank stays warmer with the basking lamp I suppose. Let the heater run and switched them over slowly this evening. They immediately swam and explored. I was worried they'd hide but any time my 5yo gets near the tank, they come running like puppy dogs! It is SO cute!

I thought for sure we had two females because I didn't see the under arm bump, but maybe one is a male. I read up real quick and it sounds like the females usually only answer? This is like a two second crickety sort of sound. Either way, I assume they are happy for now, woot!

I am going to get to the pet store as soon as I can to check out the undergravel filters (never used one before!) and to get some food variety and a light.

Thank you all for your help!
