15) Utricularia Graminifolia

The only thing you need to know about this plant… It’s carnivorous!! It actually eats small insects. Jokes aside, Utricularia Graminifolia is a pretty unique plant for many reasons. First off, it belongs to the bladderwort family, and all of them are carnivores who capture small insects with bladder-like traps (but don’t worry, it won’t eat your fish). Aside from that, It’s mostly used as a grass-like carpet for the foreground of aquariums. It’s Latin name roughly translates to “with grass-like leaves” which tells you why it’s used as a carpet. Graminifolia is known to be quite a difficult plant to grow, so it may not be the best idea to use it as a beginner. The reason for that is because it requires special care to grow fully. However, it’s still very adaptable and will survive most conditions including low light setting although it will not develop fully.

Pros: Great for “grass-like” carpets in the foreground and it’s awesome because it eats other creatures!

Cons: Hard to grow to it’s fullest potential, require a lot of knowledge and specific conditions
