So I was thinking of making my first biotope, I did some research on locations and settled for Paraguay river, it's the home of most of my fish, my black widow tetra, corydora, so on, Paraguay river is the 5th largest river in South America, 2550 km in length. It flows from Brazil through the middle of Paraguay before it makes border with Argentina and joins the Paran to merge into the large La Plata river delta. And most of the pictures I could find of the river bed are beautiful,
so I was thinking it's the perfect biotope to start with, and it may help make my fish feel more at home and comfortable, and that will make the colors of them show better, I have new bags of sand and some knot wood to start it off, so what do you all think? I have the link to a website to find out where your fish may be from if you feel like looking of doing the same
