"ever-evolving" is the perfect title... pretty much covers the nature of the hobby.
This is still my first setup attempt in this nano. There are three flatirons, the largest in the picture, numbered from left to right...
I see my tank as the third flatiron (the one on the far right) as if I was sitting on the second looking towards it.
This is also my first high-light setup and working with hc. It's definitely been the most challenging so far! I've had many smaller tanks in the past, my first being a 10 gallon ~25 years ago.
My favorite tanks have been a 120g aquarium at my daughter's Montessori elementary school, and my own 75g planted tank, setup the Walstad method with dirt substrate capped with sand, African root driftwood, pendant lights & no ferts or co2. The 75g was the tank with the gouramis, harelquins, a betta and khulis combo. I would love to have that setup again! Hopefully sooner than later.
I wish I had pictures of those tanks... they are in a box of pictures somewhere. I will need to dig them up at some point!
