Not a lot of progress, just been slowly collecting supplies I need... got a thermostat and water filter for fairly cheap online, got some free aquarium sand on craigslist, and just ordered some
biorock for the landscaping. When the rock comes I'll see if it's enough for the space. Once I have those i'll start arranging things and when they look nice I'll start putting in plants!
I have some terrarium plants for up top (caladiums, miniature philodendrons, ferns, moss) that have been growing in regular terrariums so far. It'll probably be another month or so before I can invest in aquatic plants. I'm going to try to go without CO2 and extra light. Once the plants are stable (which might require shrimp or something??) I'll get the betta - don't want to stress him out if the ecosystem crashes in the beginning!
