ya, these are all really easy to care for. Just make sure your tank gets good and stable first. You don't even need to feed them(the lights do). I'm not saying additives wont help , but they are not a necessity. About once a month all I do is dose with some type of vitamin or phyto. Just make sure you maintain a constant lighting schedule. I think my timer is from 7:30a-11:30a and then 5:30p-10p. If you get everything right, the gsp and xenia will grow like grass, something you might or might not want.
