Could someone let me know if this is blue-green algae? It covers some of my sand. I also have a hairy-looking growth on my baby tears. I currently have a sick fish, and am wondering if this algae is the culprit? I read that some type of blue-green algae let off toxins. I guess if this is the case, than the antiparasitic treatment I am using is useless.
