Fabulous shots, Wes and a nice tank too. What is its volume?
I kept freshwater tropical fish for quiet a few years in my late teens and early 20s, but gave them up when I moved away from home for work. Living in rented accommodation then prevented me continuing. Over the time when I did have aquaria I developed an interest in ‘black water’ environments, especially the flooded forest biotropes of the Amazon and Rio Negro.
During the latter stages of the pandemic I decided to set up a new tank, staying with the Rio Negro environment as a theme. The new technology available today, especially the advances made by Takashi Amano in Japan, with 'planted aquariums', make this so much easier. Once planted, I left it to establish for 6 months before introducing a single species of fish, Nannostomus marginatus: I did add some Amano shrimps and Nerite snails after a month or so to help control and algal growth though. It is now stable and the fish have been breeding and so the conditions must be right for them.
In the 70s breeding this species in captivity was pretty much impossible, and even just keeping plants alive and healthy, let alone creating lush underwater forests, could just not be done. Now, using good filtration systems, CO2 injection and pH controllers it can and I have built a control system for the tank that can even cope with me being away for 4 - 6 weeks at a time.
