There is barely any info or tanks featured and very little information, on fish and inhabitants as well. Almost no video of natural habitat.
My (80G) tank has 11 Congo Tetras and they are in a River style tank, not African though, because I had fish I needed to keep somewhere
. I spent hours looking for information, didn't come up with very much.
Thread link if interested
Shellyx member here keeps EN and might offer some information which could help, you might PM and provide this link, and see if any info would help you.
It will be fun to see you make the build!
