Hmm. Blyxa I suppose is a pretty easy plant to care for. It just needs high light and CO2
. Otherwise it's pretty much plant and forget. There are similar looking plants that are low light such as Sagittaria Subulata if you're interested.
As for the fts, tomorrow evening guys! I just tore the whole thing apart (again) in preparation for the wood haha. And yes, the fish are fine, I just took out some rocks and pulled up the stems for replanting. So it basically looks like someone dropped a weedwhacker in my tank.
