Lol don't feel bad. I'm pretty much the same. I can't even keep duck weed alive even tho it's supposed to be a nuisance plant lol. And yet I have anubias, 2 different valesenaria, 2 different lilies and Penny wort. I have em in a dirted tank and use ferts but still struggle to keep em all alive.Looks like anarcharis. Also known as water weed I believe, very easy to grow and can grow planted or floating. A lovely plant in my opinion even though I kill it every time somehow.
