Finally made the divider and started the hammocks, though I'll need suction cups, lol. Just using plastic mesh and fishing line for the hammocks, and only mesh and poster borders for the divider.
Here's Phy's current home until the 10g is ready
And here's the 10g split. Phy will be on the right (with his t-rex skull cave), and the new halfmoon on the left.
There will be live plants and a nerite snail to each side, so I may take some more of the silk plants out so it's not too crowded.
I'm using long curly bamboo canes and lucky bamboo, as they are the only semi-aquatic plant around here. Even if they don't do too terribly much, I think they look neat and I've been careful to keep leaves above water and put the roots in containers with substrate covering them. The bamboo's more of an experiment for now and so far so good.
