They were about the size of 50 cent pieces when I rescued them, but they are now at least 4" and 3.5" if not bigger. I wanted to get the larger tank for a long, long time, but I finally went to PETCO and got it. It took about a month before they got the order right and stopped selling the stand to other people when it arrived, but I just got it today. I had first tried PetSmart, but nobody would even look at me there, let alone help me. The PETCO people were really nice and attentive, but they really screwed up my order three times--it took a month to get it all correct instead of the week they had promised, but as a result they gave me almost a 50% discount on the stand. I got an oak stand and tank, and the stand cost me $279.00 (regularly $499), and the tank was about $300. I paid an extra $130 or so for a Fluval 404 canister filter for 100 gallons or less, and another $30 for a heater. In all, it was a damn lot more than I ever thought I'd spend on these turtles, but I've grown to love them, and the tank looks GREAT in our apartment. Right now I have two clamp lamps, one with a 60 watt bulb and another with a UVA/UVB bulb. My turts (Marge and Homer, although I'm not sure of their sexes yet) are LOVING it. They just moved-in today. I plan to build an enclosed box-type dock with a ramp that will sit over part of the tank (I saw a similar pic on this forum), but for now I have a floating, hollow log anchored with string and suction cups so it stays under the lights. My turts had devoured about 1/3 of their old floating turtle dock in the old 10 gallon, so this was LONG overdue. Also, I wanted to be able to show my face in TURTLE TALK again 
, so I'm glad I got the bigger tank.
FYI, the turts are barely visible in the HUGE tank, but if you look close you can see them. ALso, there is a bit of romaine lettuce floating around in there. Enjoy the pics, and I would appreciate any comments or suggestions about lighting or building my own dock.
