It's up and running! Started off just half full, this was because I didn't have a filter with capacity for the entire water volume yet, but wanted to get it going and put the cories in there so they could have the bigger footprint already. So I had it set up with fifteen gallons of water, a 50 watt heater and three filters running on airlines- my 20g capacity corner filter stuffed with media taken from the 38g's canister, and my two small extra sponge filters. These came straight out of the 10g quarantine tank, and all the contents went in here too- plastic plants, driftwood sticks, rocks, fake decor (pipe, bridge, clay arches).
On to the plants! Perry's tank donated a few rocks and small sticks, and this one free-floating vallisneria. Which is now lightly tied down to a fragment of driftwood, and seems happy enough. It's grown a bit in the few days been in here.
this one I grew from a rhizome piece. It still has a long way to go! (Plants in the back corner here are fake, I just put them in to bring over more of the beneficial bacteria)
