Well I gave up on breeding for a long while, since marina bit of a chuck of snowflakes tail (hes still pretty) and snowflake had nibbled on Marinas dorsal. Then I realized I had kingdra in his own 5g,snowflake in his own 10g, but poor marina was stuck in her 5g with 3 neons and a ghost shrimp

. So I decided I am going to switch marina and the neons with snowflake, so she can have the 10g, but I wan to make it really nice for her since its pretty bare right now. I have a few questions though because basically Im stupid.
1) What kind of live plant is that grass looking stuff, I wanted to put some of that in the tnk because its really cool looking? What other kinds of plants are good in low light (I think it came to 1.5 wpg) and doesnt look terrible.
2) I want to sand, is there some type of snail/cory that will stir the sand for me, I will still do it occasionally but I dont want to risk forgetting and killing them all, just a little help would be nice. Also so you guys know a way to make dunes or raised spots in the sand without it all falling to the bottom or falling apart.
3) I have a few options as for the stock I will add, I will either a) put in 3 more neons to give them a real shoal for once b) try to make a female sorority in the tank c) go a completely different route with some corys or a blue ram or something (I dont know Im just listing stuff).
4) Any other tips or cool ideas you guys have? Im basically starting a new tank and want it tobe more creative then my crap other one.
If anything goes wrong or outgrows I could easily aquire another 10g.
