So I just added some Cabomba to my my 20 gallon tank which is full of platies, guppies, and neon tetra... holy cow. My fish are acting like I just added a theme park to their tank. What's so great about this Cabomba to them anyway? They didn't care when I added other plants like Hornwort, and Moneywort. The Moneywort they destroyed mind you! Any idea?
