Texasreb: Thank you for the advice about the nitrates. I will definitely keep a closer eye on how clean their water is. I've been trusting my husband to do that and I don't think he's been keeping quite that close of an eye on it, although I do know he tests the nitrates weekly.
Kurtni: I also thought that this was a huge amount of growth in such a short period of time! We did decide that this was ridiculous though that we were still referring to them as little one and big one just because we don't know the gender of little one, so we gave them names tonight. Little one is Pat and big one is Tiny.

Their diet mostly consists of dry turtle food called floating food sticks for turtles. We put about 6 of these little food sticks on their floating basking area, just touching the water (so Pat will also come up to get food because Pat only every so very rarely comes up to bask) and we do this 4 days out of every 7 days. 1 out of every 7 days they also receive a few treats of a variety of earthworms, crickets, and other little bugs, all dried of course, not fresh.

Sometimes they also eat the fish food which is goldfish flakes. The plants are all gone because Tiny kept digging them up no matter how many times we kept "replanting" them, so we finally just took them out. Tiny likes to ride the bubbles, swim, and bask and likes to play with Pat. Pat just likes to sleep a lot and be left alone.
So what do you think? Is Tiny just an overachiever? Or are we feeding her too much? Tiny is definitely a female, Pat I'm not sure about. Is it possible for turtles to be anorexic? I know that sounds ridiculous, but after watching Pat tonight in the other bucket outside of the tank with crickets floating up his/her snout I started to really wonder if Pat is just flat not interested in food. We took Pat out and put a full amount of food in the bucket with her and waited for 30 minutes and at one point I walked in the room and saw a cricket floating up her snout and she moved to smell it but then turned her snout away. I don't understand why this turtle refuses to eat. We finally gave up and put Pat back in the tank. Tomorrow we will take Tiny out of the tank and put her in the bucket to eat and see if Pat will eat inside the tank since that is her habitat where she is comfortable. Obviously Tiny isn't missing any meals and we assume that she'll eat anywhere, bucket or not. I also don't understand why Pat refuses to bask. All Pat wants to do is sleep in one corner of the tank all day long. I'm a stay at home mom so I'm in view of the tank almost all day every day and I watch them full time, so I see how often Pat comes up to breathe or to bask and it is not very often. Should this be concerning? How often do they need to breathe or bask? I feel so lost because Tiny is doing everything I expect from everything I've read but Pat is the complete opposite and is beginning to worry me into thinking she's sick, especially since she's still under a year old.
