Questions on care level of a few species

[hobbzz]

I'm looking at keeping these species if it's viable, but the only places I can find with info on whether or not there is a chance of keeping them alive are the place selling them. So how easy/hard are these to care for?

Cymopolia barbata
Rhipocephalus phoenix
Halimeda opuntia
Euchema spinosum
Hetereosiphona gibessii
Laurencia iridescens
Galaxaura

Thanks in advance!

The first three are on the easier side. Basic water quality with decent lighting.

The galaxaura and h.gibessii are moderate

And my experience with the Laurencia & the euchema has not been ideal. These seem to prefer ideal water parameters and good lighting/flow. Took me 2-3 tries to keep them alive successfully

First three also require reef levels of calcium (~420) in my experience. I didn't dose calcium for a long time, and as soon as I did my C. Barbata took off. I have never had luck with any of the five varieties of Halimeda I have. All stay alive but none grow reliably.
My Galaxaura also seems mostly stagnant over the last couple months. Could by my very high nutrient levels lately.
Eucheuma does great for me, although a fairly slow grower. Moderate-high light, lots of flow although does okay in moderate/low flow.
My Gibessii died within a week of being added to my tank, but I think my nitrates were ~80ppm at that time so that's probably why!
I think I have some Laurencia that hitchhiked recently but I couldn't say how it's done yet.
