Star moss - non aquatic :(
Fissidens - a nice plant, there are a few species, I have some I jammed in a corner of my tank to hide the filter :P
Flame moss - your photo doesnt look like flame moss... flame moss should be growing in a wavy upwards manner, which gives it's the name.... I can take a picture of both for you to help you ID. it mayyyy have been grown emersed... but even my emersed flame moss have some degree of a wave to it.
Here's the flame moss, it a small stray piece that was floating around, i anchored it on the substrate for photo taking purposes...note that, despite being quite a tiny stray piece you can see the waves starting up as the moss grows...
Here is fissidens fontanus (aka phoenix moss)
It's one of the larger fissidens and has a distinct "spiky" look rather than the "fluffy" look of other mosses
You can pretty much plonk moss anywhere and they will grow... they do appreciate a good flow, especially the fissidens... so once you've tied them to something maybe try and positioning somewhere with a stronger current :)
