The correct spelling should be Hydrocotyle tripartita Japan. High tech means different things to different people. I am running a high tech tank (co2) with low light with low maintenance since dec. I am into my 3rd water change this weekend.
Other than annubias and crypts, I don't think the other plants are low maintenance. Hydrocotyle tripartita doubles or triple it's mass in 2-3 weeks and you will be looking at quite a number of trimmings per month.
