I got this one day because it looked pretty... When I got home I researched it and was pretty upset, because I assumed it would die in days.
I've had it for months in my 2gal with my betta, and today just moved it into my new 5.5gal, and its been doing great, despite my snail munching on it occasionally. Why its doing good? I dont know. I dont use fertilizers, (probably should, since I want to get a couple java ferns...) It hasn't spread much, but its alive and beautiful.
Could someone PM me and enlighten me on this fertilizer idea? It wouldn't harm my fish in any way right?
