Hello friends! I have scoured the internet and come up short on finding an answer. So I’ll ask here! Anybody have a clue on what this unwanted plant is in my tank? It’s sort of everywhere, but being dark and having dark gravel means it isn’t an incredible eyesore. My first guess is the fact that I used found driftwood from the nature preserve in this tank about a year and a half ago, and it might have interred the tank then. Any help would be so great!
