It looks like Elodia densa to me. It's fine to use with CO2 but liquid carbon melts it.
I'd float it for awhile. I'm pretty sure it doesn't like really warm temps but don't know what is the high range for it. It's considered an invasive plant by the US Gov.
It's just like anacharis, you can float it or not. You can always float some and plant some. I'd trim any dead of brown patches away.
Then leave it alone and just float it. I probably won't come back but by some slim chance it could. I still see green in the stems so it has a chance.
Try planting some then and floating some. I've floated plants under my metal halides with algae issues before.
