I really have no idea what this is. so I stuck it in the sand bed. Ignore the state of the leaves they weren't pretty when I brought them home, BUT the parts I circled are new and they've only been in the tank for a day:

LOVE the front center one, but the one in the upper right might get yanked out of it doesn't start looking better tomorrow:

the one between the 2 rocks wedge itself there so I let it be, the green one now has red tips, and the one that I have the most of still looks the same. I will try to get a better pic of #7 when the lights come on again. I'm thrilled:

same as the first pic, but closer to the front so I can get a clearer picture of the growth on it. again ignore the state of the leaf, please? lol, the only reason I kept them were because of the rhizomes/roots:

 

 

If anyone could tell me what these all are, I'd greatly appreciate it

thanks for looking everyone.

Yeah, so jealous...I'll give it a go though. These are just the macros I see in the hobby often and I'm not 100% sure where they're collected in the world, so take this with a grain of salt. I am not a macro expert, but look these up to see if they match.

 

#1: Blue Ochtodes

#2: Caulerpa prolifera

#3: Flame Algae? The shape looks right, but it dosen't have the orange tips.

#4: Don't know.

#5: Also don't know.

#6: Red Gracilaria.

#7: Don't know.
