How does a tank look with both types and is there a lot more cleaning involved or perhaps stick to keeping it simply and having one or two large Anubias?
i use both real and fake, it works ok and i use the fake ones to fill in the gaps in the tank, mainly near the back so they arent really noticed as fake.
It depends on the qualities of both the real and fake plants- as in, if the plastic plants are completely different to the real ones, they'll stick out and look naff.
