i agree with everything above. I also think hygro are good plants. A turtle would eat the plants. I know you said that you would be taking it out... I'm just saying it would eat them. As far as adding plants, it's good to acclimate them a little. You don't have to use quite as much care as you do with fish. maybe a 10 minute bath using 50/50 mix of package water and tank water. Most plants with have a justation period like a week or so where they wilt a little. Otherwise, feel free to stock up as long as you have the nutrients available. good luck.
