Actually, I think it’s rather cool looking. The green is pretty to me. Although I hate algae it looks good with those fish loving it. I love your channel and Joanna’s. You are both sincere and caring about the fish hobbyist. So many appreciate you both and your willingness to help so many when having an issue or have questions. By far, the very best fish hobbyist channel. Thank you for doing all you do. ❤️❤️
I had a 20 gallon long with 20 ember tetras. They exhibited the same schooling behavior that you're showing here. You need the larger numbers to see the fishes' true behavior.
