水草情迷

Because i live in Australia, and wanna to start feeding small fish. so want to set up a small and simple tank.
i saw from other post :

""It's very very simple, but it can work very easily and can look quite beautiful.
here's what i did when i first started an aquagrass tank quickly and successfully:
1. a 1-ft x 1-ft x 1ft tank
2. use a $22 sponge (from "ka kei") + a cheap A-A air-pump
3. ada black soil (1.5-2 inches thick)
4. a lamp (20W; I used only my table lamp); 8-10 hrs per day
5. grass: 陰性草(e.g. 小水榕, 鐵皇冠, moss) or only 蜈蚣草
6. fish: tetras (e.g. black, neon, 紅燈管, etc.), NO 小精靈 (because easy to die for a new tank)
7. a driftwood """

I want to ask wht is the english name of those 陰性草?? that i want find in Aust..
